Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.647% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cccc(N2CC(C(=O)Nc3nnc(SCCC4OCCO4)s3)CC2=O)c1
(b) O=C(CSc1nc2ccccc2[nH]1)N=Nc1c(O)[nH]c2ccccc12
(c) O=S(=O)(O)CCN1CCOCC1
(d) CCCCCNc1nc(-c2ccccc2)cs1
Answer: c. O=S(=O)(O)CCN1CCOCC1
