Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.573\% 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=C(Cc1ccc([N+](=O)[O-])cc1)Nc1nccs1
b) CS(=O)(=O)N(Cc1ccccc1Cl)c1ccc(C(=O)NCc2cccnc2)cc1
c) COCCn1c(SCC(=O)Nc2cc(C)on2)nc2ccccc21
d) CCn1c(=O)c(C(=O)NNC(=O)c2ccccc2F)c(O)c2ccccc21
e) OC(COCC(F)(F)C(F)(F)C(F)(F)C(F)F)Cn1c2ccc(Cl)cc2c2cc(Cl)ccc21
Answer: a. O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1nccs1
