Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -29.540\% 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 additional words.
Options:
a. COc1ccc(NC(=O)c2c(-c3ccccc3)noc2C)c(OC)c1
b. CSc1ccccc1NC(=O)c1ccc(Br)s1
c. CC1CN(c2ccc(C(F)(F)F)cc2[N+](=O)[O-])CCN1S(C)(=O)=O
Answer: c. CC1CN(c2ccc(C(F)(F)F)cc2[N+](=O)[O-])CCN1S(C)(=O)=O
