Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.576\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
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(Nc1ccc2c(c1)OCO2)C1CC(c2ccc(Cl)cc2)=NO1
b: CCC(=O)N(Cc1cc2ccccc2[nH]c1=O)c1ccccc1OC
c: Nc1ncn(C(=O)c2ccco2)n1
d: Cc1ccc(S(=O)(=O)N(Cc2n[nH]c(=S)n2-c2ccccc2)c2ccccc2)cc1
e: O=C(Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCCCC1)c1ccccc1
Answer: c. Nc1ncn(C(=O)c2ccco2)n1
