Answer:
Programmers can take advantage of abstraction to focus on specific tasks.
Explanation:
When we excel in some subjects, we can do abstraction in that subject. Abstraction means you understand by the term, and you do not need details of that term. Like you say some tasks will be done by a graphic designer as a project manager, and you do not need to understand at that point what he will be doing, and that is because you can write in a word or few what is going to be the outcome. And hence, the programmers can take advantage of abstraction to focus on specific tasks. And this is the correct option.
