Solution
The correct option is B Maize, Haplopappus
Endosperm is a triploid structure while shoot, as well as root apical meristem cell, has diploid composition. Maize has haploid chromosome number of 10, hence it's endosperm has 30 chromosomes in number. While Haplopappus has haploid chromosome number of 2, hence it's root apical meristem cell has 4 chromosomes. Adding a= 30 and b = 4, we get a+b = 34 which is the diploid chromosome number for apple.So, the correct option is 'Maize, Haplopappus'.
