A) It has the ability to bond with adenine.
B) It has the ability to bond with guanine.

E) It contains two nitrogenous rings.
Uracil
A nitrogenous base found in RNA, replacing thymine found in DNA.
Adenine
A purine nucleobase used in forming nucleotides of the nucleic acids DNA and RNA.
Nitrogenous Rings
Structures found in organic compounds where nitrogen atoms are part of a cyclic arrangement.

Final Answer :
A
Explanation :
Uracil is a pyrimidine base found in RNA, where it pairs with adenine through hydrogen bonding. Unlike thymine, its counterpart in DNA, uracil lacks a methyl group at the carbon 5 position. It does not bond with guanine or cytosine, and it is not a purine nor does it contain two nitrogenous rings, which are characteristics of purine bases.
