In the diagram below empty boxes show the different phases of moon as viewed from the earth. Which of the box represents the new moon?

Box D represents the new moon. This is because during a New Moon, the Moon lies between the Earth and the Sun, with its illuminated side facing away from the Earth. As a result, the Moon is not visible from Earth. A solar eclipse can also occur during this phase, but only when the Sun, Moon, and Earth are exactly aligned.
