Problem statement: Answer the multiple choice question.
Query: Which drug has a 20.289\% 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(CCCN1C(=O)/C(=C\c2cccs2)SC1=S)Nc1cc([N+](=O)[O-])ccc1O
b. COc1ccc(C)cc1NC(=O)CSc1nnc(COc2ccc(C)cc2)n1Cc1ccco1
c. O=S(=O)(c1ccc(Br)c2ccccc12)N1CCCC1
d. O=C(Nc1cccc(Cl)c1)Nc1nc(-c2ccccc2)cs1
Answer: c. O=S(=O)(c1ccc(Br)c2ccccc12)N1CCCC1
