Which of the following pairs represent bilabial plosive consonant sounds in English?

Explanation

Option A (/p/ and /b/) are bilabial plosives, produced by closing both lips and releasing a burst of air. Options B (/m/ and /v/) include a nasal and a fricative, not plosives. Options C (/t/ and /d/) are alveolar plosives, articulated with the tongue against the alveolar ridge. Options D (/k/ and /g/) are velar plosives, made with the back of the tongue against the soft palate.
