Problem statement: Answer the multiple-choice question.
Query: Which compound has a 3.820\% 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 O=C(Cc1ccccc1)Nc1nccs1
b COc1ccccc1/C=N/Nc1cc(C)nc(N2CCOCC2)n1
c Cc1ccc(SCC(=O)Nc2c(Br)cnn2C)cc1
Answer: a. O=C(Cc1ccccc1)Nc1nccs1
