Answer Details

Of the given options, 4B is the grade of pencil that is good for making dark marks. The grades of pencils range from hard (H) to soft (B), with the number indicating the degree of hardness or softness within each category. A 4B pencil is considered soft, which means it can make darker marks on paper than harder pencils like HB or 2H. Therefore, if someone wants to create dark and bold marks, they should use a 4B pencil.
