Why the answer is B, and why the others tempt you.
**The reasoning**
When a noun ends in a consonant + **y** (like "baby" — b is a consonant), we follow this rule: **drop the y and add -ies**.
- Baby → Bab**ies**
- City → Cit**ies**
- Story → Stor**ies**
This is different from words ending in a vowel + y (like "boy" or "key"), where you just add **-s** (boys, keys).
**Why the wrong options tempt you**
**A) Babys** — This looks natural because we usually just add -s for plurals. But that's the trap! The consonant-y ending demands the y→ies change.
**C) Babyes** — You might think "just add -es," but that's mixing rules. The **y must go** first.
**D) Baby** — This is still singular. No change = no plural.
**Quick takeaway**
**Consonant + y? Drop the y, add -ies.** Think: one baby cries, many bab**ies** cry. Master this pattern and you'll ace candy→candies, lady→ladies, city→cities every single time!
