• A. Sunday
• B. Thursday
• C. Friday
• D. Monday
• E. Saturday

Answer 1

The correct option is C Friday

The year 1979 is an ordinary year so it has 1 odd day.
So, the day on 12 Jan 1979 was 1 day beyond the day on 12 Jan 1980.
Given, 12 Jan 1980 was Saturday so, 12 Jan 1979 was Friday.
Hence, option (C) is the correct answer.
