Task: Answer the MCQ question.
Query: Which drug exhibits a 26.446% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(O)CCC(=O)/C=C/c1ccccc1
b. CCc1ccc(C2=NNC(=Nc3c(C)n(C)n(-c4ccccc4)c3=O)SC2)cc1
c. CCOC(=O)NCC(C#CCN(CC)CC)N(CC)CC
d. O=C(NCCSc1ccccc1)c1cncc(Br)c1
Answer: a. O=C(O)CCC(=O)/C=C/c1ccccc1
