Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.560\% 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, c, or d without using any other words.
Options:
a. COc1cccc(N(CC(=O)Nc2ccccc2C(=O)N2CCCC2)S(C)(=O)=O)c1
b. CCOc1ccc(NC(=O)C2CCN(S(=O)(=O)c3c(C)n[nH]c3C)CC2)cc1
c. COC(=O)/C(=C\c1ccc(O)cc1)c1nc2ccccc2[nH]1
d. CCN(CC)S(=O)(=O)c1ccc2c(c1)[nH]c(=S)n2CC
Answer: a. COc1cccc(N(CC(=O)Nc2ccccc2C(=O)N2CCCC2)S(C)(=O)=O)c1
