Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.373\% 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) O=C(CSc1ncn[nH]1)Nc1ccccc1-c1ccccc1
b) C=CCn1c(O)c(C(CC)=Nc2ccc(N(C)C)cc2)c(=O)[nH]c1=O
c) COc1ccc(OCCSc2nnc(-c3cccnc3)n2N)cc1
d) CCOc1ccc(NS(=O)(=O)c2cc(Cl)ccc2OC)cc1
Answer: d. CCOc1ccc(NS(=O)(=O)c2cc(Cl)ccc2OC)cc1
