Task: Answer the multiple choice question.
Question: Which compound has a 6.420\% 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.) O=C(O)CSc1nnc(-c2cccs2)n1-c1ccc(Cl)cc1
b.) Cc1ccc(-c2noc(CCC(=O)NCc3ccco3)n2)cc1
c.) CCCCOC(=O)CSc1nc2ccccc2o1
d.) CC1CCN(C(=O)c2cc3c(ccc4ccccc43)o2)CC1
Answer: a. O=C(O)CSc1nnc(-c2cccs2)n1-c1ccc(Cl)cc1
