Explanation:

Correct option is 3: Friday

The logic followed here is:
On 12th February 2011 = Saturday
12th February 2012 = Sunday
If a leap year comes immediately after an ordinary year, then the day on a certain date of the leap year will be 1 days ahead of the same date on the ordinary year upto February.
12th February 2013 = Tuesday
If a leap year comes immediately after an ordinary year, then the day on a certain date of the leap year will be 2 days ahead of the same date on the ordinary year from March to December.
In any two consecutive ordinary years, date of the next year will be one day ahead of the same date of the previous year
12th February 2014 = Wednesday
12th February 2015 = Thursday
13th February 2015 = Friday (13th February comes just after 12th February)
Hence, the correct answer is Friday.
