- BShe is not obliged to give the bell signal but must make some other efficient sound signal at intervals of not more than 2 minutes.✓ correct
- CShe is not obliged to give any sound signal because she is less than 20 meters in length.

Why B is correct
33 CFR §83.35(i) provides that a vessel of 12 meters or more but less than 20 meters in length is not obliged to give the bell signals prescribed in paragraphs (g) and (h), but if she does not, she shall make some other efficient sound signal at intervals of not more than 2 minutes. A 15-meter vessel falls within this category.
