Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.344\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccc(O[C@@H]2O[C@H](COC(C)=O)[C@@H](OC(C)=O)[C@H](OC(C)=O)[C@H]2NC(C)=O)cc1
b) C=CCNC(=S)NNC(=O)CC12CC3CC(CC(C3)C1)C2
c) CCCSc1nnc(-c2c[nH]c3ccccc23)n1C
d) Cc1ccc(N(CC(=O)NC2CCCC2)C(=O)c2nsc(Cl)c2Cl)cc1
Answer: a. COc1ccc(O[C@@H]2O[C@H](COC(C)=O)[C@@H](OC(C)=O)[C@H](OC(C)=O)[C@H]2NC(C)=O)cc1
