What type of melodic line is 1-12: stepwise, skips, leaps, or one note

I think it would be skips

Explanation:

Melodic motion in which the interval between any two consecutive pitches is no more than a step, or, less strictly, where skips are rare, is called stepwise or conjunct melodic motion, as opposed to skipwise or disjunct melodic motion, characterized by frequent skips. An interval is the distance between two pitches. ... In other words, the pitches “skip” over the interval of a step.  One may also speak of “leaps” in the melody. In the former case, one uses note to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch.
