Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 14.447\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1nnc2n(c1=O)C(CS(=O)(=O)c1ccc3ccccc3c1)CS2
b: CCOc1c(C(N)=O)cc([N+](=O)[O-])cc1[N+](=O)[O-]
c: CCOC(=O)C1=C(C)N(C)C(=O)NC1c1cc2c(cc1[N+](=O)[O-])OCO2
d: COC1=CCC2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])C2
e: CCNC(=S)N(CCc1c(C)[nH]c2ccc(Cl)cc12)Cc1ccco1
Answer: d. COC1=CCC2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])C2
