Task: Answer the multiple choice question.
Question: Which compound has a 5.277\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(CCl)NN=C(c1ccccc1)c1ccccc1
(b) N#C/C(=C\c1ccccc1)C(=O)N1CCN(c2ccccc2F)CC1
(c) CC1=NN(c2ccccc2)C(=O)/C1=C/c1c(C)[nH]n(-c2ccc(C)cc2)c1=O
(d) COc1cc(C(=O)O/N=C(\N)Cc2ccc([N+](=O)[O-])cc2)cc(OC)c1OC
Answer: a. O=C(CCl)NN=C(c1ccccc1)c1ccccc1
