General Knowledge

A mosquito's proboscis consists of six slender stylets: a labrum, a hypopharynx, a pair of mandibles, and a pair of maxillae. The mandibles have pointed tips that act like teeth, and the maxillae have fine serrations rather than discrete teeth. The number of sharp edges or serrations on the mandibles is approximately 46, which helps the mosquito pierce the skin effectively. This is consistent with entomological studies describing the mosquito proboscis anatomy and its piercing function, confirming that option A (46) is correct.
