Task: Answer the multiple choice question.
Question: Which drug exhibits a -31.433% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CN(C)c1c([N+](=O)[O-])ncn1C
(b) CCOC(=O)N1CCN(C(=O)c2ccc3c(c2)NC(=O)/C(=C\c2ccc(OC)c(OC)c2)S3)CC1
(c) Cn1cc(-c2nc3ccccc3[nH]2)c2ccccc21
(d) O=C(N/N=C/c1cc(Br)cs1)c1ccc2c(c1)OCCO2
Answer: c. Cn1cc(-c2nc3ccccc3[nH]2)c2ccccc21
