Task: Answer the MCQ question.
Query: Which drug has a -20.724\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O.O=C(NCc1nc2ccccc2[nH]1)c1ccc(Cl)c(S(=O)(=O)N2CCCC2)c1
b: O=C1CCCN1CCCn1cnc2c([nH]c3ccc(F)cc32)c1=O
c: COc1cccc(C2CC(c3cccs3)=NN2S(C)(=O)=O)c1
d: O=C(Cc1ccc(-c2ccccc2)cc1)NCc1cccnc1
Answer: d. O=C(Cc1ccc(-c2ccccc2)cc1)NCc1cccnc1
