Answer:

Option (B)

Step-by-step explanation:

By adding two polynomials,

(5xy² + 3x² - 7) + (3x²y² - xy² + 3y² + 4)

Now by adding the similar terms,

= (5xy² - xy²) + 3x² + 3x²y² + 3y² - 7 + 4

= 4xy²+ 3x² + 3x²y² + 3y² - 3

= 3x²y² + 4xy² + 3x² + 3y² - 3

Therefore, Option (B) will be the correct option.
