This question can be solved using logic,
If we have to choose 5 people, and at any given time there has to be atleast 1 business analyst and 1 computer engineer, this implies that I have to have atleast 4 of each.
Suppose I have 5 business analysts and 1 computer engineer, there is still a chance that if i choose 5 random people, they could all be business analysts - therefore, 4 is the correct answer!
Hope this helps!

This question tricks you in selecting 16 when you think how many teams you can form. However, It simply asks you to form a team (one team) which essentially means you can select 1 computer engineers and you will need maximum 4 Business Analyst to form a team of five.
Hence Answer is B.
Hence Answer is B.
