a)False. The field is fairly uniform inside the solenoid but non-uniform outside the solenoid, the field strength also decreases with increase in distance between the observer and the field.
b)True. You have more flux lines passing through a unit cross sectional area in the coil than you do outside the coil
c)False. Refer to the above.
