Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.713\% 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 other words.
Options:
a) O=C(Nc1ccc(F)c(Cl)c1)N1CCCC1
b) CC(C)NC(=O)CSCc1c(F)cccc1Cl
c) CCN(Cc1ccccc1)c1ccc(N=Nc2nn(C)c(C)c2[N+](=O)[O-])cc1
d) Brc1ccc(CSc2nnc(-c3ccco3)o2)cc1
Answer: a. O=C(Nc1ccc(F)c(Cl)c1)N1CCCC1
