The third image, present on the right side is the correct answer.
The RNA is a nucleic acid made up of nitrogenous bases adenine (A), guanine (G), cytosine (C) and uracil (U) (in DNA uracil is absent, instead of uracil thymine is present).
In the first picture, there is a thymine, which is not present in the RNA and in the second picture, the nitrogenous bases are given as R and N, which is not a code for any nitrogenous base.
The RNA sequence is complementary of the antisense DNA strand, where A binds, C bind to G and vice-versa. Hence, for the antisense DNA strand ATCGA, the correct RNA sequence would be UAGCU.
