Option 1 refers to huge Canadian forests, which are known for their expansive size and variety of tree species. These forests are found in Canada and are typically characterized by their thick vegetation and cold temperatures.

Option 2 is the correct answer, referring to the equatorial rain forests of Brazil. These forests are located primarily in the Amazon rainforest region and are known for their high levels of biodiversity. They experience a tropical climate with high rainfall and contain a wide variety of plant and animal species.

Option 3 refers to the coniferous forests of Siberia, which are found in Russia. These forests are dominated by coniferous trees such as pine, spruce, and fir, and are adapted to the cold temperatures of the region.

Option 4 refers to evergreen monsoon forests. While this type of forest does exist in certain parts of the world, it is not directly associated with the term "Selvasare."

Therefore, the correct answer is option 2, the equatorial rain forests of Brazil.
