<h3>Answer:</h3>
  • 6
<h3>Verification:</h3>

Let's verify all the options to the question. Clue given: x = 2, y = 4

Option A:

(x² + 8) ÷ y - 2

=> (2² + 8) ÷ 4 - 2

=> (4 + 8) ÷ 4 - 2

=> 12 ÷ 4 - 2

=> 3 - 2

=> 1 ≠ 6

This answer does not equal 6.

Option B:

(x² + 8) ÷ (y - 2)

=> (2² + 8) ÷ (4 - 2)

=> (4 + 8) ÷ (4 - 2)

=> 12 ÷ 2

=> 6 = 6

This answer is correct as 6 = 6.

Option C:

x² + 8 ÷ (y - 2)

=> 2² + 8 ÷ (4 - 2)

=> 4 + 8 ÷ 2

=> 4 + 4

=> 8 ≠ 6

This answer does not equal 6.

Option D:

x² + 8 ÷ y - 2

=> 4 + 8 ÷ 4 - 2

=> 4 + 2 - 2

=> 4 ≠ 6

This answer does not equal 6.

So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.
