Task: Answer the MCQ question.
Question: Which drug exhibits a 9.389\% 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, or c without using any other words.
Options:
a) O=C(COc1ccccc1-c1ccccc1)NCc1cccc(Cl)c1
b) O=C(CN1C(=O)c2ccc([N+](=O)[O-])cc2C1=O)NC1CCCCCC1
c) O=C(CSc1nnc(-c2cccs2)o1)N1CCCc2ccccc21
Answer: a. O=C(COc1ccccc1-c1ccccc1)NCc1cccc(Cl)c1
