Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.576% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(CCN(CC(=O)NC2CCCC2)C(=O)Cn2nnc(-c3ccc(C)o3)n2)cc1OC
b COc1ccc(OC)c2sc(NC(=O)C3=COCCO3)nc12
c COc1cc(S(=O)(=O)Nc2cc(C)cc(C)c2)ccc1F
d COc1cccc(NC(=O)Cn2c(CCC(=O)O)ccc2-c2ccc(Cl)cc2)c1
Answer: a. COc1ccc(CCN(CC(=O)NC2CCCC2)C(=O)Cn2nnc(-c3ccc(C)o3)n2)cc1OC
