Identify the word or words modified by the () adjectival clause.

" Jill is wearing earrings (that have gold posts) "

A. Jill

B. Is

C. Wearing

D. Earrings

The word or words modified by the () adjectival clause is earrings. So, the right answer to this question is Option D.

Explanation:

A clause which is subordinate in nature, contains an element whose elucidation is given by an antecedent on which the said clause depends grammatically is defined to be an adjectival clause. So, there is an anaphoric relation between the fortified elements present in the relative clause and antecedent on which it relies on. In this sentence, the adjectival clause performs the same function. It modifies the word 'earrings' and gives us an idea how the earrings look.
