The right answer are B (it means the letter U will replace the letter T) and C.
RNA (ribonucleic acid) is obtained from DNA through transcription.
RNA is complementary to the template strand of the DNA (antisense strand), according to Watson and Crick pairing rules (AU / T and CG) and is therefore identical to the coding strand of the DNA (sense strand), the riboses and uraciles (present only in RNA).
A hypothesis is when you make an educated guess before you complete the experiment. It is basically an inference on what might happen next. So a conclusion made based on facts.
