Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.997\% 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) Cn1c(=O)oc2cc(S(=O)(=O)NCCN3CCc4ccccc4C3)ccc21
b) CC(=O)C1=C(O)C(=O)N(c2ccc(C(=O)O)cc2)C1c1ccccc1
c) COc1ccc(-c2cc(-c3ccccc3)c3c(N)ncnc3n2)cc1
d) COc1ccc(NC(=O)CN(C)S(=O)(=O)c2ccc(Cl)cc2)c([N+](=O)[O-])c1
Answer: d. COc1ccc(NC(=O)CN(C)S(=O)(=O)c2ccc(Cl)cc2)c([N+](=O)[O-])c1
