Question

It is highly desirable that you furnished evidence of your expenses before you submit your final accounts. 

• A. It is highly desirable that you furnish evidence of your expenses.
• B. It is highly desirable that you should furnish evidence of your expenses.
• C. It is highly to be desired that you furnish evidences of your expenses.
• D. You should have to supply evidence of your expenses.
• E.

Hint:

In sentences with modal verbs like "desirable," use the base form of the verb following that. Do not add modals like "should."

Answer 1

The Correct Option is A

1. Option A: Correct, bare base form "furnish" fits the mandative subjunctive after "desirable that."
2. Option B: Redundant, "should" is unnecessary alongside the subjunctive construction.
3. Option C: Wrong, "evidences" wrongly pluralises an uncountable noun.
4. Option D: Wrong, mixes "should" and "have to" in a non-standard way.

The grammatically clean choice is option A, so the correct answer is Option A.
