Answer 1

Answer: (C)

Monday

Given, the year 1851 started with Wednesday or 1 Jan 1851 is Wednesday. Also, the year 1851 is non-leap year.
Let us find the number of odd days between 1 Jan and 23rd June.
Month Jan Feb Mar Apr May Jun
Days 30(=31 -1) + 28 + 31 + 30 + 31 + 23 = 173 days or 24 weeks and 5 odd days. So, the day on 23rd June 1851 will be the 5th day after Wednesday i.e., Monday
Hence, option (C) is the correct answer.
