is my answer correct ?

No, the option you chose is wrong. Salad dressing is a suspension & the oil & the particles gets settled when left undisturbed (2nd option.) Oil & water (the other particles) are immiscible, so it's a suspension. Some salad dressings can be a colloid as well. But, the 2nd option suits better here.Your answer is wrong because in a suspension, the particles are big & aren't informally distributed throughout the mixture. That's only in a solution/colloid. Suspensions have particles that are unevenly distributed & are big enough to scatter light until they settle down (Tyndall effect).

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun

The answer to this would be choice b (diplod)
