Question

Among the following, which one is a bilabial sound?

• A. /p/
• B. /b/
• C. /m/
• D. All of the three

Answer 1

Answer:

D. All of the three

A bilabial sound is produced by bringing both lips together.

• /p/ – voiceless bilabial plosive

• /b/ – voiced bilabial plosive

• /m/ – voiced bilabial nasal

All three sounds /p/, /b/, and /m/ are articulated using both lips, so they are all bilabial sounds.
