Explanation:

CubeSats are basically miniature satellites which typically weigh around two kilograms. In the future, they have potential to carry out tasks like imaging and remote sensing currently performed by heavier satellites which are expensive to build and launch. It was recently in news because US scientists have developed micropropulsion system based on liquid water for orbital manoeuvring of CubeSats which shall prolong their operational life in space before becoming space debris. The propulsion system has been named as Film-Evaporation MEMS Tunable Array or FEMTA. Hence, answer is d.
