a. Both structures (a) and (b) are left-handed.
b. Structure (a) is right-handed. Structure (b) is left-handed.
c. Structure (a) is left-handed. Structure (b) is right-handed.
d. Both structures (a) and (b) are right-handed.

Answer 1

d. Both structures (a) and (b) are right-handed. Structures (a) and (b) are both right-handed.

Step-by-step explanation:

Structures (a) and (b) are both types of DNA structures. DNA is a right-handed double helix, meaning it twists in a rightward direction. So, both structures (a) and (b) are right-handed.
