Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.849\% 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 or b without using any other words.
Options:
(a) Cc1c(-c2ccc(F)cc2)nc(N)c(C#N)c1-c1cccnc1
(b) Cc1ccc(NC(=O)OC(C)CNC(=O)Oc2cccc(C)c2)cc1
Answer: a. Cc1c(-c2ccc(F)cc2)nc(N)c(C#N)c1-c1cccnc1
