( I) were

(II) is

(III) are

(IV) have been​

Answer 1

A pair of cotton trousers are in the cupboard.

• One of the more difficult situations of subject-verb agreement is phrases containing a pair of or binary nouns, such as trousers and binoculars.
• One reason for this is because pair and trousers are both two-part words that might be difficult to pronounce.
• Worse, nouns with the plural suffix "s," like pants and scissors, cause the proximity criterion to be applied incorrectly.
