According to the 2001 census, the male literacy rate in India was 75.85 percent. This means that 75.85 percent of the male population in India at that time was literate.

Option 1, 45.96 percent, is incorrect as it represents a lower literacy rate than the actual data.

Option 2, 56.38 percent, is also incorrect as it is lower than the correct answer of 75.85 percent.

Option 4, 64.13 percent, is wrong as well, as it is also lower than the correct answer.

The correct answer is therefore option 3, 75.85 percent, which represents the actual male literacy rate in India according to the 2001 census.
