Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.971\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) COC(=O)C(=O)/C=C(\O)c1ccc(C)cc1
b) COc1ccc(CN2C(=O)c3cccnc3C2=O)cc1S(=O)(=O)NCc1ccc(C)o1
c) CCC12CN(C(=O)c3ccc(C)cc3)CC(CC)(CN(C(=O)c3ccc(C)cc3)C1)C2=O
d) O=C(Cn1c(=O)cnc2ccccc21)NC1CCC(O)CC1
e) O=C(Cc1ccc([N+](=O)[O-])cc1)N1N=C(c2ccncc2)CC1(O)C(F)(F)F
Answer: a. COC(=O)C(=O)/C=C(\O)c1ccc(C)cc1
