A quick identification method is to look at the function of the clause. If it behaves like a noun, it is a Noun Clause. If it describes a noun, it is a Relative Clause. If it modifies a verb or gives information about time, reason, place, or condition, it is an Adverbial Clause. If it specifically introduces a condition using words like if or unless, it is a Conditional Clause.
Step 1: Identify the function of the Noun Clause.
A noun clause is a subordinate clause that performs the same function as a noun within a sentence.
It may act as:
• Subject of a sentence
• Object of a verb
• Object of a preposition
• Complement of a verb
Examples:
• What he said was true.
• I know that she is honest.
• The problem is whether they will agree.
In each example, the highlighted clause functions as a noun.
Looking at List-II, statement (ii) says:
Functions as a noun within a sentence.
Therefore,
\[
(a) \rightarrow (ii)
\]
Step 2: Identify the function of the Adverbial Clause.
An adverbial clause modifies a verb, an adjective, or another adverb. It provides additional information regarding:
• Time
• Place
• Reason
• Purpose
• Condition
• Contrast
• Manner
Examples:
• We left when the meeting ended.
• She stayed home because she was ill.
• He works hard so that he may succeed.
These clauses provide circumstances surrounding the action.
In List-II, statement (iii) states:
Modifies a verb, adjective or adverb (time, reason, condition, etc.).
Hence,
\[
(b) \rightarrow (iii)
\]
Step 3: Identify the function of the Relative Clause.
A relative clause is also known as an adjective clause because it modifies a noun or pronoun.
It usually begins with relative pronouns such as:
\[
\text{who, whom, whose, which, that}
\]
Examples:
• The boy who won the prize is my friend.
• The book that I purchased is interesting.
• The house which stands on the hill is beautiful.
In every case, the clause describes or modifies a noun.
List-II statement (i) says:
Modifies a noun and usually begins with who, which, that.
Therefore,
\[
(c) \rightarrow (i)
\]
Step 4: Identify the function of the Conditional Clause.
A conditional clause expresses a condition that must be fulfilled for another action or event to occur.
Such clauses are commonly introduced by:
\[
\textit{if, unless, provided that, in case}
\]
Examples:
• If it rains, we will stay indoors.
• Unless you study, you may not succeed.
• If she arrives early, we will begin the meeting.
These clauses establish a condition for the main clause.
List-II statement (iv) reads:
Expresses a condition often introduced by if or unless.
Thus,
\[
(d) \rightarrow (iv)
\]
Step 5: Form the final matching sequence.
Combining all the correct matches:
{lcl}
(a) Noun clause & $\rightarrow$ & (ii)
(b) Adverbial clause & $\rightarrow$ & (iii)
(c) Relative clause & $\rightarrow$ & (i)
(d) Conditional clause & $\rightarrow$ & (iv)
Therefore,
\[
a - ii,\quad b - iii,\quad c - i,\quad d - iv
\]
This arrangement corresponds exactly to Option (A).
