DNA is the material within the cell that regulates and controls cellular activity
B
DNA is used by the cell to fight off bacterial infections
C
DNA provides energy for photosynthesis
D

Explanation: 

Detailed explanation-1: -DNA now has three distinct functions-genetics, immunological, and structural-that are widely disparate and variously dependent on the sugar phosphate backbone and the bases.

Detailed explanation-2: -Hershey and Chase’s experiments proved that DNA, not proteins, was the genetic material since proteins lack the most important character of the genetic material, which is replication. In a human cell, the genetic material is present in the form of double-stranded DNA molecules, forming the shape of a double helix.
