A levelling is carried out to establish the Reduced Levels (RL) of point $\mathrm{R}$ with respect to the Bench Mark (BM) at P. The staff readings taken are given below.
If $\mathrm{RL}$ of $\mathrm{P}$ is $+100.000 \mathrm{~m}$, then $\mathrm{RL}$ (in $\mathrm{m}$ ) of $\mathrm{R}$ is
(A) 103.355
(B) 103.155
(C) 101.455
(D) 100.355
