Please explain in details (I mean step by step)

Question 9 (10 points,): Consider the following images. Although the AES is a very secure modern symmetric block cipher, in ECB mode, the encrypted image has significant information about the unencrypted image. Using this example, explain the drawbacks of encryption in ECB mode and suggest a mode of operations in order to have better result of encryption. Give a detailed description of the mode of operation you choose. Hint: CBC,OFB,CFB,CTR) Y: Encrypted image (by ECB mode) is composed of X: Original image is composed of n blocks, eachimage of n encrypted blocks, each 128 bits long. 128 bits long. Y-(Y1, Y2, . . , Yn) where Yk-AES(%) . Question 9 (10 points,): Consider the following images.
