Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.857\% 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 other words.
Options:
a.) Cc1cc(Br)c2[nH]c3c(c2c1)CCCC3=O
b.) CCCC(=O)c1cc(-c2nc3ccccc3n2C)n(C)c1
c.) COc1ccccc1N1CCN(C(=O)C2c3ccccc3Oc3ccccc32)CC1
d.) O=C(O)/C=C/c1ccccc1[N+](=O)[O-]
Answer: d. O=C(O)/C=C/c1ccccc1[N+](=O)[O-]
