A
Make a collection of only 1 if the plant is sterile
B
Create a collection of 4 duplicates
C
Creates 5 collections
D
Create 3 collections
Explanation: 

Detailed explanation-1: -Collect at least 25 leaves, one leaf (or two in the case of wheat) from each plant, randomly across the entire area. When analyzed, the plant tissue analysis can confirm the adequacy of nutrients or identify the inadequacy (or less often toxicity) of one or more nutrients.

Detailed explanation-2: -Remove one or two leaves from the mid-portion of new shoot growth. Remove a total of 50 leaves for each sample. No more than 10 trees should be used for a sample. If two or more trees are used per sample, they should represent a cross section of the variety for the area.

Detailed explanation-3: -The recommended stage of growth to sample is just prior to the beginning of the reproductive stage for many plants. Roots from total plant sample should be removed. It is well to take a soil sample from the same area at the same time.
