Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.155\% 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(OC1CN2CCC1CC2)c1ccc([N+](=O)[O-])cc1
b: Cc1ccc(NC(=S)N(Cc2cccs2)Cc2cc3cc(C)ccc3[nH]c2=O)cc1
c: CC(=O)N/C(=C\c1ccc(Cl)cc1)C(=O)O
d: Cc1c(C(=O)NC(C)C2CC3CCC2C3)cccc1[N+](=O)[O-]
Answer: c. CC(=O)N/C(=C\c1ccc(Cl)cc1)C(=O)O
