Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 13.486\% 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: COc1ccccc1NS(=O)(=O)c1cccc(C(=O)N2CCN(C(=O)c3ccco3)CC2)c1
b: S=c1[nH]nc(-c2ccco2)n1/N=C/C(Cl)=C/c1ccccc1
c: COc1ccc2c(CCNC(=O)/C=C/c3ccc(OC)c(OC)c3)c[nH]c2c1
Answer: b. S=c1[nH]nc(-c2ccco2)n1/N=C/C(Cl)=C/c1ccccc1
