While doing his experiment,Millikan one day observed the following charges on a single drop:
$(i)$ $6.563 \times 10^{-19} \ C$
$(ii)$ $8.204 \times 10^{-19} \ C$
$(iii)$ $11.50 \times 10^{-19} \ C$
$(iv)$ $13.13 \times 10^{-19} \ C$
$(v)$ $16.48 \times 10^{-19} \ C$
$(vi)$ $18.09 \times 10^{-19} \ C$
From this data,the value of the elementary charge $(e)$ was found to be:

• A
  $1.641 \times 10^{-19} \ C$
• B
  $1.630 \times 10^{-19} \ C$
• C
  $1.648 \times 10^{-19} \ C$
• D
  $1.602 \times 10^{-19} \ C$
