Answer:
C
Step-by-step explanation:
Being denied all access to the phone and computer for an entire semester or until his grades improve should not be placed in the contract.
Instead of denying him all access to the phone and computer, his parents can put other measures in place to see that his grades improve. There should be restrictions and limitations on the time he spends on social networks. They can do this by setting screen time limits and setting rules on when it is appropriate to use social networks. Jonah on his own should also be time conscious and know his time limits.
Losing all rights to his phone and computer can trigger stress and anxiety.
