Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 25.316\% 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, b, or c without using any other words.
Options:
[a] O=c1[nH]c(CSc2ncnc3sc(-c4ccccc4)cc23)nc2ccccc12
[b] O=C(NC(=S)Nc1ccccc1)c1cccs1
[c] O=C(Nc1ccccc1)OCCNC(=O)c1ccccc1
Answer: a. O=c1[nH]c(CSc2ncnc3sc(-c4ccccc4)cc23)nc2ccccc12
