Erica

Step-by-step explanation:

The given expression is 8x^2y+4xy .

The prime factorization of the first term is

$8x^2y=2^3\cdot x^2\cdot y$

The prime factorization of the second term is

$4xy=2^2\cdot x\cdot y$

The greatest common factor is product of the least powers of the common factors.

$GCF=2^2\cdot x\cdot y=4xy$

Therefore Erica is correct.
