Answer:
4th Option is correct that is 3i.
Step-by-step explanation:
We are given with a graph with real axis and imaginary axis.
A complex number is also plotted on graph.
We need to find the Imaginary part of the complex number plotted on the graph.
Coordinate of the point from the graph is ( -2 , 3 )
We know that standard form of complex number is ,
z = real part + imaginary part( containing i )
From graph -2 is on real axis and 3 is on imaginary axis.
So, Complex Number , z = -2 + 3i
Therefore, 4th Option is correct that is 3i.
