Task: Answer the multiple-choice question.
Query: Which compound has a -1.905\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. CC(=O)NC(NC(C)=O)c1ccc(Br)cc1
b. CC1(c2ccccc2)NC(=O)N(CC(=O)NC(=O)NC2CCCC2)C1=O
c. O=S(=O)(c1ccc(Cl)cc1)n1nnc2ccccc21
Answer: a. CC(=O)NC(NC(C)=O)c1ccc(Br)cc1
