Task: Answer the MCQ question.
Question: Which compound has a -0.134\% 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 additional words.
Options:
a) O=c1cnn(Cc2c(Cl)cccc2Cl)c2ccccc12
b) COc1ccccc1N(CC(=O)N/N=C/c1c(O)ccc2ccccc12)S(C)(=O)=O
c) O=C(c1cc([N+](=O)[O-])cc([N+](=O)[O-])c1)N1CCCc2ccccc21
d) COc1ccc(C(C)=O)cc1COC(=O)Cn1cnc2ccccc2c1=O
e) CCS(=O)(=O)c1ccc2c(c1)N(S(C)(=O)=O)CC(C(=O)NCc1ccccc1OC)O2
Answer: a. O=c1cnn(Cc2c(Cl)cccc2Cl)c2ccccc12
