Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.798\% human ether-à-go-go related gene (hERG) inhibition at 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(COCc1nc2ccccc2c(=O)[nH]1)NC1CCCC1
b: COc1ccc(C(=O)C2(C)N(O)C(C)C(c3cccs3)=[N+]2[O-])cc1
c: COc1cc(/C=C2\C(=O)NN(c3ccccc3)C2=O)ccc1OCC(N)=O
d: CCc1nc2nc(C)c(NS(=O)(=O)c3ccc(F)cc3)c(=O)n2[nH]1
e: COc1cccc(S(=O)(=O)NCc2ccc(C(=O)Nc3ccc(Cl)cc3)cc2)c1
Answer: a. O=C(COCc1nc2ccccc2c(=O)[nH]1)NC1CCCC1
