Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.804\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CSc1nnc(-c2ccccc2Cl)n1N
(b) Cn1c(=O)n(Cc2ccccc2F)c(=O)c2c1nc1n2CCN1Cc1ccco1
(c) C=CCOC(=O)CCP(=O)(CCC(=O)OCC=C)c1ccccc1
(d) O=C(CN1CCN(S(=O)(=O)c2cccc(Cl)c2)CC1)N1CCCCC1
Answer: a. CSc1nnc(-c2ccccc2Cl)n1N
