<h2>The required "option D) 54 + 42 = 6(9 + 7)" is correct.</h2>

Step-by-step explanation:

We have,

The sum of 42 and 54

= 42 + 54

∴ 42 and 54

42 = 2 × 3 × 7 and

54 = 2 × 3 × 3 × 3

The greatest common factor of 42 and 54

= 2 × 3

= 6

∴ 42 + 54

= 6(7 + 9)

= 6(9 + 7)

Thus, the required "option D) 54 + 42 = 6(9 + 7)" is correct.
