Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.233\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(Nn1cnnc1)c1cc2c(s1)CCCC2
b) COc1ccccc1C(=O)n1nc(C)cc1C
c) Cc1cc(C2C(C#N)=C(N)Oc3n[nH]c(C)c32)c(C)s1
Answer: a. O=C(Nn1cnnc1)c1cc2c(s1)CCCC2
