Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.146\% 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 other words.
Options:
a: C=CCn1c(SCC(=O)Nc2ccccc2C)nc(O)cc1=O
b: COc1ccc(S(=O)(=O)N2CCCCCC2)cc1C(=O)N(C)Cc1ccco1
c: CC1CC(=O)Nc2ccccc2N1C(=O)CSc1nnnn1C(C)C
d: COc1ccccc1NC(=S)N(CCN1CCOCC1)Cc1ccccc1F
Answer: a. C=CCn1c(SCC(=O)Nc2ccccc2C)nc(O)cc1=O
