How would you go about solving this? its supposed to be simple?

This is Kirschoff's law - No charge, and so current, accumulates at a node (junction between wires). So the sum of all the currents going in must equal to the sum of all the currents going out.

I stands for current

Its not A becuase that says - I2+I3+I4=I1

Its not B because that says - I1+I4=I2+I3

Its not D because that says - I1=I2+I3+I4

Its C becuase the current comes from I1 and I2 to meet at the middle and leaves at I3 and I4 directing away from the middle

Long story short:
Magnitude of Inwards arrows must equal Magnitude of Outwards arrows

Edit: Relative to the node.
