D
The grid initiall attracts electrons from the anode because it it psitively charged in relation to the anode. By varying the charge on the grid you can control the electron flow. As the electrons near the approach the grid they are attracted to the more positive charge on the cathode and most continue through the grid to the cathode. A small number flow through the grid. The number attracted by the cathode divided by the number attracted by the grid gives you the gain of the triode it is when used as amplifier. It operates like a bipolar junction transistor

B
because if the grid was kept positive it would repell the electrons and keep them away from the cathode.

CORRECT ANSWER IS: ATTRACTED TO THE ANODE INSTEAD OF THE GRID
