An object is moving to the right with speed vi when a force of magnitude F is exerted on it. In which of the following situations is the object’s direction of motion changing and kinetic energy decreasing at the instant shown? So, I know that this (pic attached) is the answer, but I don't really understand why. Can someone please provide an explanation for it? Thank you!

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
