btw the answer says c but how is that possible

shouldnt it be B?? this is from the 2020 paper right?
A always pairs with T so cant be C.
Double-stranded molecule means that nitrogenous bases pair up meaning there's equal % of A/T and C/G- each strand contains 25% of Adenine and 25% of Guanine

 

[IDK and IDC]

aight so basically, the dna structure is a double helix or in this case double stranded. in a dna adenine matches with thymine and guanine matches with cytosine to make the "double stranded dna".
so the answer is B
this question is from 2020 hsc bio, it isnt c
