Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.767\% 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 additional words.
Options:
[a] CC(=O)Nc1ccc(NC2CCCCC2NS(=O)(=O)c2ccccc2)cc1
[b] CCO/C=C/C(=O)N(C)CCC#N
[c] COc1ccc(/C=C/C(=O)NC(=S)NN2CCCCC2c2cccnc2)cc1OC
Answer: b. CCO/C=C/C(=O)N(C)CCC#N
