Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.438\% 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: Nc1[nH]n2c(=O)c3c(nc2c1N=Nc1ccc(Cl)cc1)CCCC3
b: C/C(=N\O)c1ccc2[nH]ccc2c1
c: Cc1ccc(NC(=O)CSCc2cc(=O)n3nc(C4CC4)sc3n2)cc1
d: Cc1ccc(C(F)(F)F)cc1NC(N)=S
Answer: a. Nc1[nH]n2c(=O)c3c(nc2c1N=Nc1ccc(Cl)cc1)CCCC3
