Solution

The correct option is D Magnesium-24
$M g - 24$ is the most common naturally occurring isotope of magnesium.
Magnesium found in nature is about 79% $M g - 24$ , 10% $M g - 25$ , and 11% $M g - 26$ .
Since, $M g - 24$ isotope has maximum abundance, the average atomic mass of Mg will be close to 24.
