Problem statement: Answer the multiple choice question.
Query: Which compound has a 6.971\% 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 or b without using any additional words.
Options:
a COC(=O)CSC1=NN1c1cc(C)nc(N)n1
b O=C(CNS(=O)(=O)c1c(F)cc(F)cc1Br)OCC(=O)N1CCCC1=O
Answer: a. COC(=O)CSC1=NN1c1cc(C)nc(N)n1
