Task: Answer the multiple choice question.
Query: Which drug has a 1.686\% 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 N#C/C(=C\c1ccc(OCC(N)=O)cc1)S(=O)(=O)c1ccccc1
b COc1cc(NS(=O)(=O)c2cc3[nH]c(=O)c(=O)[nH]c3cc2C)cc(OC)c1OC
c COc1ccc(S(=O)(=O)N2CCN(C(=O)c3sccc3-c3ccccc3)CC2)cc1
Answer: b. COc1cc(NS(=O)(=O)c2cc3[nH]c(=O)c(=O)[nH]c3cc2C)cc(OC)c1OC
