Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.600\% 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 CN(c1ccc(C(=O)NCCSCc2ccccc2)cc1)S(=O)(=O)c1ccccc1
b Cc1cc(C)cc(NC(=S)N2CCC(NC(=O)c3ccccc3C)CC2)c1
c COc1cc(C#Cc2c(-c3ccccc3)n(C)c3ccccc23)cc(OC)c1
Answer: c. COc1cc(C#Cc2c(-c3ccccc3)n(C)c3ccccc23)cc(OC)c1
