The last option is the correct answer.
{RAW is a file format that captures all image data recorded by the sensor when you take a photo. ➡[It simply means the analog photos which is captured by camera is simply digitized and shown in computers, mobiles.,etc with the help of RAW file format.]
WHY RAW FORMAT?
When shooting in a format like JPEG image information is compressed and lost. Because no information is compressed with RAW you’re able to produce higher quality images, as well as correct problem images that would be unrecoverable if shot in the JPEG format.}
