Explanation:

- Option 1: "very"

- If you say "Rita is very smart to start playing cricket now," it emphasizes her high level of intelligence, suggesting she is making a wise decision. However, this does not fit logically into the structure "Rita is ____ smart to start playing."

- Option 2: "too"

- If you say "Rita is too smart to start playing cricket now," it implies that she is overly intelligent, suggesting that starting cricket might not be the best use of her talents.

- Correct Answer

- Option 3: "much"

- "Rita is much smart to start playing cricket now" is grammatically incorrect, as "much" is not used directly with adjectives like "smart."

- Option 4: "more"

- "Rita is more smart to start playing cricket now" is grammatically incorrect. It requires "smarter" for correct comparative form usage.
