Question
Read the analemma and match the solar declination to dates.
For most of these, there are two dates possible because the subsolar point moves across that latitude twice during the year....so you have to look at both sides of the loop on the analemma.

This is a pretty direct question. All we need to do is look for the latitude on the left side of the fraph and follow the grid till it intersects the analemma and find the corresponding date. There are two dates for all latitudes, but only one among them is given in the options. Following are those dates.
1. E - December 22
2. A - October 30
3. B - March 1
4. F - April 4
5. D - July 30
6. C - June 1
