Solution

The correct option is A
According to Einstein's photoelectric equation,

$e V_{0} = E - ϕ = h ν - ϕ$

$\Rightarrow V_{0} = \frac{h}{e} ν - ϕ$

Comparing the above relation with the equation of straight line,
$y = m x - c$

Therefore, the graph between $V_{0}$ and $ν$ will be a Straight line with a positive slope and negative $y$ intersect.

Hence, option $(A)$ is correct.
