Why did indian muslims believe that the indian national congress could not meet their needs

They were the minority in India. They believed that they would not get fair treatment from the Hindu majority.  They also believed that issues such as poverty, health, prejudice and oppression were not being tackled by the Congress. When the British left the country it was inevitable that the Muslims would separate from India and form their own country Pakistan.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.

i would say the executive branch is because the executive branch is in charge of enforcing the laws and judicial branch is in charge of enforcing but the executive branch is most responsible for it all so i would have to say the executive branch.
