As per the properties of field lines we know that

1. Electric field lines originates from positive charge and terminates at negative charge

2. number of field lines originated outwards is directly proportional to the magnitude of charge

So here we can say that number of field lines linked with charge A is more than B so magnitude of charge A will be more

Also we can see that field lines are originated out from charge A and terminated in charge B so charge A is positive and charge B is negative

so the correct answer will be

A). The signs on charges A and B are opposite. The amount of charge on A is greater than that on B.
