#A

#B

#C

#D

Explanation:
Mainnets often have stricter gas limits and higher costs than testnets. A function that runs fine on testnet may exceed block gas limits in production. Developers should simulate deployments and optimize loops before mainnet release

#A

#B

#C

#D

Explanation:
The fallback() function runs when a transaction calls a non-existent function or sends data without matching any signature. It’s essential for proxy contracts but must be written carefully to avoid gas griefing and reentrancy risks.
