The correct answer is - A. The Baltic Sea.
The second biggest Russian city, St. Petersburg, is located on the shores of the Baltic Sea, more specifically, on the westernmost part of the Baltic Sea, where the sea gets the furthest inland and creates a bay-like shape. It is great importance for the city that comes out on this sea because through it, it is connected with the like of Finland, the Scandinavian countries, as well the Baltic countries, Poland and Germany, and this is of great importance for the economy of this great city.
Many fossils remain buried
Rocks contain the history of life...
Btw the animal ones don't count i think cuz fossils can be anything like teeth, bones or anything not just animals it can be formed by leaves as well so just for extra guidance i believe the ones that state animals are probably not the options to choose due to the fact that fossils are not just living organisms they're anything that has been buried and decomposed over many years and layers of sediments cover it over many years compression may alter the shape of the fossil aswell!
Hope that extra info helps for a bit of guidance!
