Answer:
The correct answer is letter "A": Wait until he enters an area with an available wired network.
Step-by-step explanation:
It is common that while driving on the road there might be some areas where internet connection can be lost because the antennas of the service provider our mobile lines work with are not nearby. Then, just like in Jojo's case, we should wait to enter into an area where there is enough signal so we can use our mobile internet as usual.
