Explanation:

The assertion is correct and the reason provided is not accurate.

The Income Tax Act in India was indeed introduced in 1860, but it was not intended as a temporary measure. The reason for its introduction was to meet the financial requirements of the government. The act was initially applicable only to income from land revenue, but it was later extended to cover other sources of income.

The introduction of income tax was primarily driven by the need for revenue to meet the administrative and developmental expenses of the British government in India. While the revenue generated may have been used for various purposes, the idea that it was introduced specifically to promote Western education is not the primary reason for the inception of income tax in India. The utilization of revenue for different purposes was determined by the government's priorities at different points in time.
