B 
In the following Figures $\left (a\right )$ and $\left (b\right )$, each number inside a small triangle is the sum of the numbers inside in the neighbouring small circles. The number inside each circle is either $1$, $2$, $3$, $4$, $5$, $6$, $7$ or $8$.  The sum of whole numbers inside the circles in Figure $\left (a\right )$ is $1+8+8+2+3+5=27$. What is the largest possible sum of whole numbers inside the circles in Figure $\left (b\right )$?
