Solution:

Given quadratic equation is 2x^2 + 8x + m3 = 0.

Let us assume that the roots of the given quadratic equation are equal.

Then, the discriminant of the quadratic equation will be equal to zero.

Discriminant = b^2 - 4ac, where a = 2, b = 8, and c = m3.

Therefore, (8)^2 - 4(2)(m3) = 0

64 - 8m3 = 0

8m3 = 64

m3 = 8

m = 2

Hence, the value of m is 2.

Therefore, option (D) is the correct answer.
