Explanation:

- Option 1: Largest share

- The "lion’s share" commonly refers to the largest portion or the majority of something. This idiom originates from a fable where a lion takes the largest portion of a hunt.

- Correct Answer

- Option 2: Animal’s share

- This option is incorrect. The idiom does not refer to just any animal's share, but specifically signifies a significant, dominant portion, much like how a lion would take the lead.

- Option 3: Limited share

- This is incorrect as well. Instead of a limited portion, the idiom implies receiving the most significant part available.

- Option 4: Forceful share

- Although the lion may take a share by force, the phrase itself doesn’t focus on the method of obtaining it. The crucial aspect is the size of the share.
