The Correct Option is A
Solution and Explanation
If a light ray travels from oil to glass then,
$\Rightarrow\, \frac{\mu_{oil}}{\mu_{glass}}=\frac{V_{glass}}{V_{oil}}$
$\Rightarrow\, \frac{2}{3}\times2 = \frac{V_{glass}}{V_{oil}}=\frac{4}{3}$
Then velocity of light in glass is $\frac{4}{3}$ of velocity in oil.
