(D) In an exclusive class interval (or continuous series),the lower limit is included in the class,but the upper limit is excluded.For the class interval $30-45$:- The lower limit is $30$,which is included in this class.- The upper limit is $45$,which is excluded from this class and is instead included in the next class interval (e.g.,$45-60$).Therefore,the value $45$ is not included in the class $30-45$.

Class	$4-7$	$8-11$	$12-15$	$16-19$
Frequency	$5$	$4$	$9$	$10$
