Explanation:

Going through & comparing both the proposed budget with the revised budget, we observe 2 changes. We notice that 5% was reduced from purchase of new musical instruments for the music department and that upgrade of computer lab hardware was increased by 5%. As the revised budget is the final budget, we see that in it the board opted to have more  computer hardware instead of new instruments for the music department. In so doing, Northville Schoolpurchased more computer hardware at the expense of new instruments.

Opportunity cost refers to the "cost" incurred by foregoing the advantage associated with the best alternative choice to get something else. In this case, the Northville School Board passed up the opportunity to get new instruments & instead opted to upgrade the computer lab hardware. Therefore, the opportunity cost for computer lab hardware upgrade is the purchase new instruments.

i think the answer is a and i hope this ; ))
