Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.646\% 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 CCS(=O)(=O)N1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1
b COc1cccc(-n2cnnn2)c1
c CC(=O)N1CCN(c2ccc(NC(=O)c3ccccc3Br)cc2Cl)CC1
d COc1ccc(N2C(=O)C(Cc3ccccc3)NC2=S)cc1
Answer: a. CCS(=O)(=O)N1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1
