Answer:
A) bat wing and human hand
Explanation:
Homology in biology is existence of the shared ancestry between the pair of structures or the genes present in the different taxa.
<u>The most common example of the homologous structures is forelimbs of the vertebrates, where wings of the bats, arms of the primates, front flippers of the whales and forelegs of the dogs and the horses are all derived from same ancestral tetrapod structure. </u>
Homologous structures can be explained by evolutionary biology which states that these are adapted to the different purposes as result of the descent with the modification from common ancestor.
<span>1. D dripstone produced by buildup of minerals precipitated from groundwater.
Water drips down from, for example, the roof of a cave and slowly leaves behind mineral deposits which form a shape similar to an icicle
2. D running water cuts small channels into a slope
Rill erosion is formed by soil removal from small streams of running water. They form based on how the water falls down a slope and tend to migrate to already depressed or softer areas of soil.</span>
