Task: Answer the multiple choice question.
Query: Which drug has a -2.129\% 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(Nc1ccc(Br)cc1)Nc1ccccc1F
b Cc1cnc(C(=O)Nc2ccccc2-n2cccc2)cn1
c Nc1cc(N)nc(SCC(=O)NNC(=O)c2ccc(Cl)cc2)n1
Answer: c. Nc1cc(N)nc(SCC(=O)NNC(=O)c2ccc(Cl)cc2)n1
