Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.126\% 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(NN=C1CCN(Cc2ccccc2)CC1)c1cc(Br)ccc1O
b) O=CN1CCN(C(=O)COc2ccc(Cl)cc2Br)CC1
c) O=C(Nc1cccc(Cl)c1)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
d) CCOc1ccccc1CN1CCN(CCCn2cccn2)CC1CCO
e) CC(=O)CSc1nnc(-c2ccc(S(=O)(=O)N3CCOCC3)cc2)n1C
Answer: a. O=C(NN=C1CCN(Cc2ccccc2)CC1)c1cc(Br)ccc1O
