Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -13.929% 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, d, or e without using any additional words.
Options:
a. O=C1Cc2cc([N+](=O)[O-])ccc2N1c1c(Cl)cccc1Cl
b. O=C(O)Cc1ccc2ccc3ccccc3c2c1
c. Cc1nc2ccc3nc(NC(=O)c4ccc5c(c4)OCCO5)sc3c2s1
d. COc1ccc(C2CC(c3ccccc3)=NN2C(=O)COC(=O)C2CC2)cc1
e. CN1C(=O)CSc2ccc(NC(=O)N3CCC(N4CCCCC4)CC3)cc21
Answer: a. O=C1Cc2cc([N+](=O)[O-])ccc2N1c1c(Cl)cccc1Cl
