Solution

The correct option is C
north pole

The way to find out the polarity of a solenoid is:

Imagine the solenoid being held by the right hand. If the four fingers encircling the solenoid show the direction of current, the thumb indicates the north pole.

Here, the direction of current is same as that of encircling fingers. So, this end of the solenoid is north pole.
