Answer - Deoxyribose
Since the picture contains Cytosine, Guanine, Adenine and Thymine. It is a Deoxyribonucleic Acid (DNA). If it were to be Ribonucleic Acid (RNA), the base Uracil would have been present instead of Thymine. Since the nucleic Acid is DNA, the sugar present is DEOXYRIBOSE.
P.S - If it were to be Uracil, the nucleic acid will be RNA, and the sugar will be RIBOSE.
