Final answer:
Flea larvae are most likely to be found in the carpet because it provides a dark, protected environment with ample organic material for them to feed on.
Step-by-step explanation:
Flea Larvae Habitats
The question you're asking relates to flea larvae and their preferred habitats within the home environment. Considering the options presented, flea larvae are most likely to be found in the carpet (Option C). Flea larvae require a protected environment with ready access to organic material to feed on, which is typically found in carpets due to the accumulation of pet hair, human skin cells, and other organic debris. Conversely, flea larvae are unlikely to thrive in a drain, in a potted flower, or in a bed to the same extent because these environments do not provide the same level of sustenance and protection.
Flea larvae go through several stages before becoming adults, and during their larval stage, they are blind and avoid light, which makes them burrow deep into carpet fibers where it is dark and where their food sources are abundant. This characteristic behavior, combined with their need for a somewhat stable environment, makes carpets an ideal breeding ground for flea offspring.
