Task: Answer the multiple choice question.
Question: Which compound has a 14.873\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COCCn1c(=S)[nH]c2sc3c(c2c1=O)CCCC3
b. CC1CN(c2ccc([N+](=O)[O-])cc2Cl)CCN1S(C)(=O)=O
c. Cc1ccc(-c2nc(CN(CC3CCC3)CC3CCCO3)c(C)o2)s1
Answer: a. COCCn1c(=S)[nH]c2sc3c(c2c1=O)CCCC3
