Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.041\% 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) CN1C(=O)c2c(sc3c2CCCC3)NC1c1ccccc1O
b) CC(C)N1CCc2c(sc(NC(=O)c3ccc(S(=O)(=O)N(C)CC4CCCO4)cc3)c2C(N)=O)C1.Cl
c) O=C(NC1CCCCC1)N1CCC(c2nc3ccccc3[nH]2)CC1
Answer: a. CN1C(=O)c2c(sc3c2CCCC3)NC1c1ccccc1O
