Task: Answer the MCQ question.
Question: Which drug exhibits a 7.543\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COC(=O)c1ccccc1N=Nc1c(C)n[nH]c1C
b: COc1ccc(-n2c(=S)[nH]c3cc(C(=O)N4CCN(c5ccccc5)CC4)ccc3c2=O)cc1
c: COc1ccc2[nH]c(=O)c(-c3nnn(-c4ccc(Cl)nc4)n3)cc2c1
Answer: a. COC(=O)c1ccccc1N=Nc1c(C)n[nH]c1C
