Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 0.554\% 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] C=CCn1c(SCc2ccccc2)nc(O)cc1=O
[b] CSc1ccccc1NC(=O)CN(C)CC(=O)Nc1ccccc1C(F)(F)F
[c] CN(C)C1=NC[C@H](Cc2ccccc2)N1CC1CCCC1
Answer: a. C=CCn1c(SCc2ccccc2)nc(O)cc1=O
