The correct option is A A converging lens
Refractive index of medium, μ1=1.33
Refractive index of lens, μ2=1.5
Let radius of curvature of the first surface be R.
Then, the radius of curvature of the second surface will be −R.
Using Lens Maker's Formula;
Since f is positive, parallel rays will form image to the right of the lens. Hence, it will behave as a convergent lens.
