Answer:
Answer b) is correct: the tropics are 25N and 25S, and the tilt is 25° for Mars.
Explanation:
The definition of the Arctic Circle is the circumference containing the area where, in the northern's summer solstice, it is wholly sunlit, while it is wholly dark (not reached by sunlight) in northern's winter solstice. (This reasoning may be followed for the Antarctic circle and the southern's summer and winter, by means of an analogy).
The existence of Arctic (and Antarctic) Circle is due to the planet's axis's tilt with respect to its revolution plane around the central objetc, i.e., our common Sun. <u>The angular distance of the Arctic Circle from martian's geographic North Pole is the same as Mars tilt value</u>. So, if the Arctic Circle is located 65° North, that means it is 65° away from the equator, and 90°-65° = 25° from the North Pole. This variable, called co-latitude, is complementary to the latitude (being 90° the sum of these two values, always).
So, the tilt value must be 25 degrees, which in turn means that the tropics must be at that same angular distance from the equator, both North and South. So the tropics are 25N and 25S. Answer b) is correct.

The ocean floor and its depth vary a lot from place to place. Maybe it is expected that the central parts of the oceans would be the deepest parts of them, while the closer the ocean floor is to the land it will be shallower, but that is not the case.
The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges. There is constant propelling of magma, and as the magma cools off quickly it creates new crust. This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.
The further away we move from the mid-ocean ridges, or rather being closer to the oceanic margins, the depth actually increases. The reason for this is the erosiove power of the water, but also the subduction zones. The erosion manages to flatten the ocean floor, thus making it deeper, while the subduction zones are the places where the oceanic plate is moving downward toward the mantle, and it create ocean trenches which are very deep, in fact the deepest parts of the oceans.
So your answer is C)
the common name for the British Indian Empire was the British Raj. The British East India Company ruled India until the rebellion in 1867 which then brought direct rule from the British Government.
