Answer #1

B is the answer.

Explanation:

* DNA is double stranded in nature. One of the standard is template stand and another one strand is coding strand.

* the DNA polymerase bind to the strand and leads to the synthesis of DNA by the action of DNA polymerase.

*DNA consists of nucleotides. Nucelotide consists of Deoxyribose sugar, phosphate group and nitrogenous bases.

* Nitrogenous bases are adenine, thymine, guanine and cytosine. Uracil is not found.

* The backbone is made up of Deoxyribose sugar and phosphate group.

​​​​​​​That's why answer is B.
