$\begin{array}{|c|c|c|}
\hline Q & T U & M U \
\hline 0 & 0 & - \
\hline 1 & 25 & \mathrm{~A} \
\hline 2 & \mathrm{~B} & 15 \
\hline 3 & 53 & \mathrm{C} \
\hline 4 & \mathrm{D} & 10 \

\hline
\end{array}$
A) 11.
B) 61.
C) 81.
D) 8.

Marginal utility (MU) is the change in total utility (TU) from consuming one additional unit. From 4 to 5 units, TU increases from D to 71. Since D is 61 (71 - 10 = 61), the change in TU from 4 to 5 units is 71 - 61 = 10. Therefore, E, which represents the MU from consuming the 5th unit, must be less than 10 because MU typically decreases as consumption increases. The only option less than 10 is 8.
