Identify the underlined phrase in each sentence and match it with its correct type.

Column A	Column B
A. The heavy grocery bag slipped from her hand in the kitchen.	(i) Noun Phrase
B. He finished his breakfast quite quickly before leaving for office.	(ii) Adjectival Phrase
C. The spare keys under the doormat are useful in emergencies.	(iii) Adverbial Phrase
D. She felt a bit nervous while waiting for her interview results.	(iv) Prepositional Phrase

In sentence A, heavy grocery bag works as a noun phrase because it names the thing that slipped.

So,
A $\to$ (i)

In sentence B, quite quickly modifies the verb “finished”, so it is an adverbial phrase.

So,
B $\to$ (iii)

In sentence C, under the doormat begins with the preposition “under”, so it is a prepositional phrase.

So,
C $\to$ (iv)

In sentence D, a bit nervous describes the subject “She”, so it is an adjectival phrase.

So,
D $\to$ (ii)

Therefore, the correct matching is:

a-(i), b-(iii), c-(iv), d-(ii)
