Final answer:
A diploid organism has two sets of chromosomes. Neither statement A nor statement B is true.
Step-by-step explanation:
A diploid organism has two sets of chromosomes in its somatic cells. In the case of the eukaryotic organism mentioned, its somatic cells possess 40 chromosomes, indicating that it is a diploid organism.
Therefore, statement B: 'An individual with 50 chromosomes exhibits euploidy' is false, as the organism described has 40 chromosomes, not 50. Additionally, statement A: 'A triploid individual would have 60 chromosomes' is also false. A triploid individual would have three sets of chromosomes, resulting in a total of 3n chromosomes, not 60. Therefore, the correct answer is d) Neither A nor B.
