The answer is student 1.
Student 1 said that RNA is not deoxyribose but ribose. Student 1 also noted that RNA do not contain thymine but contains Uracil.. It is very obvious that student 1 correctly noted the characteristics of an RNA.

NOTE: In RNA, the pentose sugar is ribose and not deoxyribose. <span>RNA contains uracil in place of thymine.</span>

The answer is; student 1

The reason RNA is a ribose sugar is because it’s pentose rings have an H, rather than an OH in DNA, in their 2’ carbon. DNA has deoxyribose sugar in comparison. In addition, rather than having Thymine base (bases attach to the 1’ carbon in the rings), like in DNA, this base is replaced by Uracil (so Uracil binds complementarily to Adenine in RNA).
