Answer: B

[[math]] \begin{aligned} & e_{40}=e_{40: 20}+{ }_{20} p_{40} \cdot e_{60} \\ & =18+(1-0.2)(25) \\ & =38 \\ & e_{40}=e_{40: 11}+p_{40} \cdot e_{41} \\ & \Rightarrow e_{41}=\frac{e_{40}-e_{40: 11}}{p_{40}}=\frac{e_{40}-p_{40}}{p_{40}}=\frac{38-0.997}{0.997}=37.11434 \end{aligned} [[/math]]
