Answer:
The correct option is A. Complementarity.
Explanation:
The Complementarity is a way to compare two equals leveled things in more than one different way.
Both two comparisons are fit in their own way and both have their own significance.
Complementarity will fit with each other as similar things will be adjusted easily.
It can be elaborated with an example:
If India is exporting some goods to China for a high rate and Chine is also exporting some goods to India at high rate so these both conditions will satisfy the economic conditions of these countries equally.
In the same way, If the project will be evaluated either vie terms of their strategic fit with the existing project or with their ability with the current product family, both will result in the same manner.
