Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 17.575\% 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, or c without using any other words.
Options:
a COc1ccccc1-c1c(C)oc2cc(OC(=O)c3ccco3)ccc2c1=O
b Cc1ccc(S(=O)(=O)Nc2cccc(-c3ccc(N4CCCCCC4)nn3)c2)cc1
c CC1=Nn2c(nc(-c3ccccc3)c2-c2ccccc2)NC(=O)C1Br
Answer: a. COc1ccccc1-c1c(C)oc2cc(OC(=O)c3ccco3)ccc2c1=O
