Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 20.887% 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) Cc1oc(=O)c(NC(=O)c2ccccc2)cc1C(N)=O
b) Cn1c2c(c3ccccc31)CC/C2=N\O
c) O=C(COc1cccnc1[N+](=O)[O-])c1ccc(Cl)s1
d) COc1ccc(OC)c(S(=O)(=O)NCCc2csc(-c3cccnc3)n2)c1
e) CNC(=O)C1CC(=O)N(c2ccc(OCC(=O)NCc3ccccc3)cc2)C1
Answer: c. O=C(COc1cccnc1[N+](=O)[O-])c1ccc(Cl)s1
