What is the difference between stem plot and histogram plot?

(a) No difference

(b) Histogram does not have negative values while stem may have negative values

(c) Histogram cannot relate 3 variable while stem can

(d) Histogram cannot be created in MATLAB

I have been asked this question in an online quiz.

This is a very interesting question from Statistics in chapter MATLAB Basics of MATLAB

Correct choice is (b) Histogram does not have negative values while stem may have negative values

To elaborate: Histograms are used to see the frequency distribution of a variable to show the frequency of a class over any interval. So, naturally, a variable cannot repeat with a negative frequency. Stem plot only relates the two arguments it gets in terms of their projected values. So stem() can have negative values.
