The patient went into cardiac arrest. The (-ac) portion of the word is a/an

A. noun suffix
B. plural suffix
C. combining form
D. adjective suffix

To determine the answer, let's break down the word "cardiac" and focus on the (-ac) portion:

1. Start with the base word: "cardi". This refers to the heart.

2. Add the combining form "-ac" to "cardi". This form is typically used to create an adjective, meaning "pertaining to" or "related to".

Based on this analysis, we can conclude that the (-ac) portion of the word "cardiac" is an adjective suffix.

Therefore, the correct answer is D. adjective suffix.
