Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.878\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) Nc1nnn(CC(=O)N/N=C/c2cn[nH]c2-c2ccccc2)n1
(b) Cc1cc(C)c2c(N)c(-c3nnc(SCc4ccc(Cl)cc4)n3C)sc2n1
Answer: a. Nc1nnn(CC(=O)N/N=C/c2cn[nH]c2-c2ccccc2)n1
