Solution

The correct option is A Upper strata older and lower younger
When they are first shaped, extrusive molten rocks (magma streams and volcanic cinder) will be more youthful than the sedimentary shakes beneath them and will be more seasoned than the sedimentary rocks which in this way frame above them.
So, the correct option is 'Upper strata older and lower younger'.
