Task: Answer the multiple choice question.
Query: Which compound exhibits a -24.147% 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 CCn1ncc(C(=O)Nc2cccc(Cl)c2)c1C
b Cc1cccc(CNC(=O)c2cc(S(=O)(=O)N3CCOCC3)cn2C)c1
c CCOC(=O)CNC(=O)COc1coc(CN2CCN(c3ccccc3)CC2)cc1=O
d COc1ccc(CCNC(=O)CN2C(=O)NC(CCSC)C2=O)cc1
Answer: a. CCn1ncc(C(=O)Nc2cccc(Cl)c2)c1C
