Task: Answer the multiple choice question.
Query: Which drug has a 9.544\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC1(C)CC2(CCO1)NCCN1C(=O)CSC12
b: O=C(COc1cccc2ccccc12)Nc1nc2ccccc2[nH]1
c: O=C(Nc1ccccc1F)c1cc2c(s1)-c1ccccc1S(=O)(=O)C2
d: O=C(CCc1nnc(-c2ccccc2)o1)c1ccc(Cl)cc1
Answer: a. CC1(C)CC2(CCO1)NCCN1C(=O)CSC12
