Task: Answer the MCQ question.
Query: Which drug exhibits a -0.290\% 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, or d without using any other words.
Options:
a.) COc1ccc(NS(=O)(=O)c2cccc(C(=O)NCC(c3ccccc3OC)N3CCCC3)c2)cc1
b.) COc1ccc(N(CC(=O)Nc2cc(C)on2)S(=O)(=O)c2cc(C)ccc2C)cc1
c.) CN(C)/C=C1/C(=O)Nc2ccccc21
d.) O=C(CN1C(=O)c2ccccc2C1=O)Oc1ccc(Cl)cc1
Answer: c. CN(C)/C=C1/C(=O)Nc2ccccc21
