Final answer:
The Nehru Report revealed an exclusionary Hindu mentality, leading Quaid-e-Azam to pursue Pakistan, marking a split from Indian unity.
Step-by-step explanation:
The Nehru Report disappointed Quaid-e-Azam because it rejected separate electorates for Muslims, signifying the exclusionary attitude of Hindu leadership and confirming Jinnah's fears of minority marginalization, leading to his demand for a separate nation. Mohammad Ali Jinnah perceived the Nehru Report as evidence of an underlying bias in Hindu leadership towards Muslim political aspirations.
Despite earlier cooperation between Hindus and Muslims for Indian self-rule, the report, which advocated for a united India without recognizing the separate political interests and safeguards for Muslims, furthered the divide. This eventually led to Jinnah's commitment to creating Pakistan, marking a definitive split from the idea of a single, unified India.
