Task: Answer the MCQ question.
Query: Which drug exhibits a 15.424\% 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=c1cc(CSc2ccc(Cl)cc2)nc(-c2ccccn2)[nH]1
b. COC(=O)c1ccc(CSc2nc3ccccc3c(=O)n2Cc2ccco2)o1
c. O=C(Cn1[nH]c(=O)c2ccccc2c1=O)OCC(=O)c1ccc(F)cc1
d. O=C(NCc1ccccn1)c1cccc(NS(=O)(=O)c2ccc(Br)cc2)c1
Answer: a. O=c1cc(CSc2ccc(Cl)cc2)nc(-c2ccccn2)[nH]1
