Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.
What is Tiktaalik?
Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).
The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.
The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.

Answer:
D
Explanation:
So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).
So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function
