Multiple Choice

Flea larvae develop best at greater than 75% relative humidity.

Explanation:
Flea larvae need a moist environment to develop. High humidity helps prevent desiccation as they feed on organic debris in carpets and soil, allowing them to molt and grow more efficiently. When relative humidity stays above about 75%, larvae have better survival and faster development. If humidity drops, especially well below 75%, their development slows and mortality increases. Among the options, the level above 75% is the condition that best supports larval development, so the correct choice is greater than 75%. Keeping indoor humidity lower can help slow flea development as part of control efforts.
