Question

which of the following orders is classified by arm, hand and extra long finger bones covered with a membrane which resembles a wing?\
artiodactyla\
carnivore\
aero\
chiroptera

Explanation:

The question is about classifying an order based on arm, hand, and extra - long finger bones covered with a membrane like a wing. Among the options, "Chiroptera" (bats) have such a structure with their wing membranes supported by elongated finger bones (arm, hand, and finger bones structure for flight). Artiodactyla are even - toed ungulates, Carnivora are carnivorous mammals, and the "Arm" option is likely a typo or incorrect. So Chiroptera is the correct classification.

Answer:

Chiroptera (the option in the blue box, labeled "Chiroptera")
