A container has a vertical tube, whose inner radius is 20.00 mm, connected to it at its side, as shown in the figure. An unknown liquid reaches level A in the container and level B in the tube-level A being 5.0 cm higher than level B. The liquid supports a 20-cm high column of oil, between levels B and C, whose density is $900 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ The density of the unknown liquid is closest to
A) 3600 kg/ $m ^ { 3 }$
B) 3900 kg/ $m ^ { 3 }$
C) 2800 kg/ $m ^ { 3 }$
D) 3100 kg/ $m ^ { 3 }$
E) 3300 kg/ $m ^ { 3 }$
