What is the religion of Zubin Mehta?

Zubin Mehta was born as Zoroastrian in Bombay, India (Today, in India, this ancient Iranian religion is called Parsi) . Following the conquest of Iran where the religion of Zaratushtra was born and prevailing, by Muslim Arabs, many adherents of that religion fled to India, resettled especially in Bombay and continued freely practicing their faith. I think Zubin Mehta was born to a family of this Parsi community.
