Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.512\% 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. CCCCOc1cccc(C2/C(=C(\O)c3ccc4c(c3)OCCO4)C(=O)C(=O)N2CCN2CCOCC2)c1
b. Cc1onc(C(=O)N2CCN(c3ccccc3)CC2)c1[N+](=O)[O-]
c. CCCCCN1CC(O)=C(c2nc(-c3ccc(Cl)cc3)cs2)C1=N
d. COC(=O)c1nn(-c2ccccc2)c(=O)cc1Oc1ccccc1
e. COc1ccccc1OCCCOc1ccc([N+](=O)[O-])cc1Cl
Answer: d. COC(=O)c1nn(-c2ccccc2)c(=O)cc1Oc1ccccc1
