Suppose an electron in some atom absorbs energy and transitions from level 1 up to level 4. which of the following is a true statement regarding the electron transitions back down to level 1?

The transition from energy level 4 to energy level 2, followed by a transition from energy level 2 to 1, is possible. This is because transitioning from a higher level to lower level can be done various ways. In other words transitions in the downward direction can be any number of levels.

Explanation:

It is easier to make transition from higher levels to lower levels because emitting some amount of energy which depends on the the energy level the electron is transitioning to. Unlike downward transitions, the energy level an electron can transition to is limited by the amount of energy made available to it for absorbtion. That is, the amount of energy required to excite it to that state or energy level.
