Task: Answer the multiple choice question.
Query: Which drug has a 18.577% human ether-à-go-go related gene (hERG) inhibition at 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=C(N/N=C1\C2CN3CCN(C2)CC1(c1ccccc1)C3)Nc1ccccc1
b: CCNC(=S)N/N=C/c1ccccc1[N+](=O)[O-]
c: COCCn1c(SCCOc2ccccc2)nc2ccccc2c1=O
d: CCCCOc1ccc(C(C)NC(=O)C2CCCN(S(=O)(=O)CCC)C2)cc1
e: Cl.O=C(Oc1cccnc1)c1ccc(Cl)cc1
Answer: b. CCNC(=S)N/N=C/c1ccccc1[N+](=O)[O-]
