Aprintf("%");

Bprintf("%%");

Cprintf("%percent");

Since % is a special character in format strings, to print a literal % you use %%.
Step 2: Analyze other options
printf("%percent"); is invalid syntax, printf("%"); is incomplete, printf("\%"); uses backslash which is not recognized for % in printf.
Final Answer:
printf("%%"); -> Option B
Quick Check:
Use %% to print % literally in printf [OK]

Quick Trick: Use double %% to print a single % in printf [OK]
