Which PROC PRINT step correctly displays only the first 10 observations in the data set?

Option A is correct. The (obs=10) option is used as a data set option within the proc print statement

to limit the number of observations processed to the first 10. The syntax should be placed

immediately after the data set name within parentheses. Options B, C, and D are incorrect because

they either use the wrong option or place the obs option incorrectly outside of the parentheses or

with incorrect syntax.
