Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 9.980\% 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(c1cnccn1)N1CCN(c2ccccc2F)CC1
[b] O=C(CCC(=O)Nc1ccc(Br)cc1)N/N=C/c1ccc(F)cc1
[c] CC(=O)Nc1ccc(/C(C)=N/NC(=O)c2ccccc2Cl)cc1
[d] N#Cc1ccccc1NC(=O)COC(=O)CCc1ccccc1
Answer: a. O=C(c1cnccn1)N1CCN(c2ccccc2F)CC1
