A container has a vertical tube, whose inner radius is 12.00 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 $320 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ The gauge pressure at level B is closest to
A) 630 Pa
B) 310 Pa
C) 470 Pa
D) 790 Pa
E) 940 Pa
