Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 3.868\% 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) O=C(Cc1c[nH]c2ccccc12)NCc1ccco1
b) O=C(CSc1nc2ccccc2s1)Nc1nccs1
c) CN(C(=O)c1cccc(C(=O)N(C)c2ccccc2)c1)c1ccccc1
d) Cc1ccc(C)c(Nc2c([N+](=O)[O-])c(=O)oc3ccccc23)c1
Answer: d. Cc1ccc(C)c(Nc2c([N+](=O)[O-])c(=O)oc3ccccc23)c1
