Task: Answer the multiple choice question.
Question: Which drug has a -2.600\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(c2cccnc2)C1
b O=C(NC1CCCC1)C(c1ccco1)N(Cc1ccccc1)C(=O)c1csnn1
c CC(=O)N1CCCN(Cc2nc(C3(c4ccc(C)cc4)CCCC3)no2)CC1
Answer: b. O=C(NC1CCCC1)C(c1ccco1)N(Cc1ccccc1)C(=O)c1csnn1
