Task: Answer the multiple choice question.
Question: Which drug has a 18.694\% 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, or d without using any additional words.
Options:
a. Cc1c(N=C2SCC(=O)N2/N=C/c2ccccc2Cl)c(=O)n(-c2ccccc2)n1C
b. O=C(Cn1cnc([N+](=O)[O-])c1)Nc1cc(Oc2ccc(Cl)cc2Cl)cc([N+](=O)[O-])c1
c. NC(=O)c1ccc(C23CC4CC(CC(C4)C2)C3)o1
d. CCC(=O)N1CCc2cc(S(=O)(=O)CCC(=O)Nc3ccc(OC)cc3)ccc21
Answer: d. CCC(=O)N1CCc2cc(S(=O)(=O)CCC(=O)Nc3ccc(OC)cc3)ccc21
