Question

Find out the correct preposition to be used in the blanks. He is capable ________ solving the complicated issue.

• A. in
• B. with
• C. to
• D. of

Hint:

Differentiate between ``capable of'' (takes a gerund) and ``able to'' (takes an infinitive verb).
This distinction is highly tested in competitive language examinations.

Answer 1

The Correct Option is D

Step 1: Identify the key adjective.
The adjective in the sentence is "capable", and we need the correct preposition to follow it.
Step 2: Apply the fixed prepositional phrase rule.
"Capable" always collocates with "of" in standard English. Phrases like "capable in", "capable with", or "capable to" are grammatically incorrect.
Step 3: Complete the sentence.
"He is capable of solving the complicated issue" is the grammatically correct and natural construction.
\[ \boxed{\text{of}} \]
