Task: Answer the MCQ question.
Query: Which drug has a 7.810\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(NNC(=O)c1c(O)c2ccccc2[nH]c1=O)c1ccccc1Br
b COc1ccc(C(=O)NNC(=O)C2=NN(c3ccccc3)C(=O)CC2)cc1
c O=C(CNC1CCCC1)Nc1ccc(N2CCCCCC2)cc1.O=C(O)C(=O)O
d COc1ccc(O)c(/C=N/NS(=O)(=O)c2ccc(C)cc2)c1
e COC(=O)CC(NC(=O)C1CC1)c1ccc2c(c1)OCO2
Answer: a. O=C(NNC(=O)c1c(O)c2ccccc2[nH]c1=O)c1ccccc1Br
