Task: Answer the MCQ question.
Question: Which drug has a 4.388% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=CN1N=C(c2ccccc2)CC1c1ccccc1[N+](=O)[O-]
b) COc1cc(/C=N/NC(=O)C2=NNC(=O)C2C)ccc1O
c) CCc1nc(-n2[nH]c(=O)c3ccccc3c2=O)c2c3c(sc2n1)CCCC3
d) CNC(=O)C1(C)C=CCN1C(=O)c1ccccc1
e) O=C(Oc1ccc2ccccc2c1)C1CC(=O)N(c2ccc(Br)cc2)C1
Answer: a. O=CN1N=C(c2ccccc2)CC1c1ccccc1[N+](=O)[O-]
