Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.625\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) Cc1ccc2nsnc2c1NC(=O)c1cccc([N+](=O)[O-])c1
b) Nc1nc(-c2ccc([N+](=O)[O-])cc2)c(C(=O)Nc2ccc(Cl)cc2)s1
c) O=C1CCc2cc(S(=O)(=O)Nc3ccccc3Cl)ccc2N1
d) C[C@]12CCC(=O)CC1CCC1C2CC[C@@]2(C)C1CC[C@@]21CCO1
e) C=CCn1c(SCC(=O)c2[nH]c(C)c(C(=O)OCC)c2C)nc2scc(-c3ccccc3)c2c1=O
Answer: c. O=C1CCc2cc(S(=O)(=O)Nc3ccccc3Cl)ccc2N1
