Let’s go through each question one by one. We’re looking for the word where the underlined “s” sound is pronounced differently — either as /s/ (like in “cats”) or /z/ (like in “dogs”). The rule is:
- If the word ends in a voiceless sound (like p, t, k, f, th), the “s” sounds like /s/.
- If the word ends in a voiced sound (like b, d, g, v, m, n, l, r, or any vowel), the “s” sounds like /z/.
We’ll check each option carefully.

B. carts → ends in “t” (voiceless) → /s/
