Task: Answer the MCQ question.
Question: Which drug exhibits a 1.689% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. COc1ccc(/C=C/C(=O)OCC(=O)Nc2cc(S(=O)(=O)N(C)C)ccc2Cl)cc1
b. Clc1ccccc1CNc1ncnc2nc[nH]c12
c. Cc1cccc(Nc2nnc(SCC(=O)Nc3ncc(C(F)(F)F)cc3Cl)s2)c1C
d. O=C(CNC(=O)c1ccc2c(c1)OCCO2)N/N=C/c1ccc([N+](=O)[O-])cc1
e. O=C(Nc1ccccc1Cl)c1ccccc1Cl
Answer: e. O=C(Nc1ccccc1Cl)c1ccccc1Cl
