1. “a letter from mahatma gandhi to his cousin- 1915”
2. “autobiography: the story of my experiments...- 1948”
3. “gandhi urges calm should be seized- 1922”.
and the rest are secondary
Explanation:
the question states Gandhi lived from 1869 to 1948. each answer has a year after it so really the only answers that make sense are the ones that were recorded while he was still alive so that he could confirm them.
