To answer this question, you need to understand how to correctly reference a macro variable in a TITLE statement in SAS.
Let's go through each option to understand why it is correct or incorrect:
Option A) title "Total Sales for ’&month’ ";
This option is incorrect because the macro variable month is not correctly referenced. The single quotes around &month are unnecessary and would cause the macro variable to be treated as text rather than a reference.
Option B) title "Total Sales for ’month’";
This option is incorrect because the macro variable month is not correctly referenced. The single quotes around the word "month" are unnecessary and would cause the word "month" to be treated as text rather than a reference.
Option C) title "Total Sales for &month";
This option is correct because the macro variable month is correctly referenced without any unnecessary quotation marks or single quotes.
Option D) title Total Sales for "&month";
This option is incorrect because the macro variable month is not correctly referenced. The double quotes around "&month" would cause the macro variable to be treated as text rather than a reference.
The correct answer is C. This option is correct because it correctly references the macro variable month without any unnecessary quotation marks or single quotes.
