Step-by-step explanation:
The statement is false. The Congress and the Muslim League did not reject the Montague-Chelmsford Reforms. In fact, they both played significant roles in shaping and supporting these reforms.
The Montague-Chelmsford Reforms were introduced by the British government in 1919 and aimed to increase Indian participation in the governance of British India. They provided for the expansion of the legislative councils and granted some limited powers to the Indian nationals.

The Muslim League also participated in the discussions and negotiations surrounding the reforms and sought to safeguard the interests of the Muslim community.
