Red light is the best for plants.

The correct answer is red as photosynthesis rate is fastest in blue and red light.

Rate is maximum in red light.

While photosynthesis is maximum in blue color.

You are absolutely right @Aaheli Ghosh.

If someone has the knowledge of enhancement effect then he will come to know that although rate of photosynthesis is higher maximum in red light then followed by blue and then other colors but when they are given together the rate increases.

Interesting point is that suppose we have rate unit as simple number e.g, for red 2 and for blue 3 and when they are given together it should be 2+3=5 but interestingly it will greater than 5.
i.e, 6 or something else greater than 5 this is called enhancement effect.

Hopefully, I could explain the fact behind the answer white light is the correct answer and one-word explanation is enhancement effect.

White light has all 7 colours red blue green yellow etc. So white light increase the photosynthesis because sun provided white light.

I think red is the correct answer. Because there is an experiment to check the photosynthesis is maximum with monochromatic light especially with far red and red in spectrum.

Red light is the correct answer.

In which part of the plant the maximum process photosynthesis takes place?

Yes, It's white light.
