Answer:
A. a dependent variable.
Step-by-step explanation:
A scientific experiment contains three types of variables (factor or condition) in experiments: the dependent, independent and controlled variables.
The independent variable is the variables which can be changed or altered naturally or artificially like the sunlight, temperature whereas a dependent variable is a variable which depends on the independent variable and is the studied parameter of the experiment.
In the given question, since the production and the number of the seeds is influenced by the pollinator, therefore, a number of seeds will be considered the dependent variable.
Thus, Option-A is the correct answer.
