Why each option
Steganography hides data payloads inside image files, requiring analysis tools to extract the concealed information.
The word 'pontine' is not present in the steganographic payload extracted from Image_4240.png.
Analyzing Image_4240.png with a steganographic extraction tool reveals the encoded string 'prolific' embedded within the file's binary data. Steganography techniques such as LSB (least significant bit) encoding embed payload bytes into image pixel data without visually altering the image. The hidden word is recoverable only by applying the appropriate decoding method to the file.
The word 'abysmal' is not encoded within the image file's hidden data stream.
The word 'petroleum' is not the hidden string embedded inside Image_4240.png.
The word 'mushroom' is not present in the steganographic payload of this image file.
The word 'Chicago' is not encoded within the binary data of Image_4240.png.
The word 'marshmallow' is not the hidden string recoverable from this image file.
The word 'flying' is not present in the steganographic data embedded within Image_4240.png.
The word 'shocking' is not encoded inside the image file's hidden data.
