Electron is a particle having a

A
negative charge of one unit and zero mass
B
positive charge of one unit and zero mass
C
negative charge of one unit and a mass of about $9.1 \times 10^{- 31} kg$
D
negative charge of one unit and a mass of about $1.67 \times 10^{- 27} kg$

Solution:

Electron has one unit negative charge $(- ve) .$

Cathode rays consist of a stream of negatively charged particles called electrons.

Mass of electron $m_{e} = \frac{e}{\frac{e}{m_{e}}}$

$= \frac{1.602 \times 10^{19} C}{1.75882 \times 10^{11} C / kg}$

$= 9.1094 \times 10^{- 31} kg .$
