Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.049% 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) O=C(Cc1ccccc1)NCC(=O)N/N=C/c1ccc(Cl)cc1
(b) Cc1occc1C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
(c) Cc1cccc(OC(=O)c2ccncc2)c1C
(d) COc1ccc(C(=O)O/N=C(\N)c2ccc(OC)c(OC)c2)c(OC)c1
Answer: a. O=C(Cc1ccccc1)NCC(=O)N/N=C/c1ccc(Cl)cc1
