Month	Revenue (in Lacs)
January	50
February	65
March	75
April	80
May	95

Help Rohan to complete the code.

______ as plt #Statement−1 
Months = ['January', 'February', 'March', 'April', 'May']
Revenue = [50, 65, 75, 80, 95]
______ #Statement-2
plt.xlabel('Months')
plt.ylabel('Revenue')
______ #Statement-3
______ #Statement-4
plt.legend()
plt.show()

1. Write the suitable code for the import statement in the blank space in the line marked as Statement−1.
2. Write the suitable code for the blank space in the line marked as Statement−2, which plots the line graph with the appropriate data and includes a label for the legend.
3. Fill in the blank in Statement-3 with the correct Python code to set the title of the graph.
4. Fill in the blank in Statement-4 with the appropriate Python code to save the graph as an image file named monthly_revenue.png.
