Answer 2

1) Milk is a natural, whole food made up of water, protein, fat, carbohydrates in the form of lactose, vitamins including calcium, minerals including phosphorous and a range of other bioactive compounds. ... When light hits these casein micelles it causes the light to refract and scatter resulting in milk appearing white.
2) The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
3) When we see the Sun at sunrise or sunset, when it is low in the sky, it may appear yellow, orange, or red. But that is only because its short-wavelength colors (green, blue, violet) are scattered out by the Earth's atmosphere, much like small waves are dispersed by big rocks along the shore.
4) it's a alloy actually you can say it but as you have compound in options,you should go for that because the brass consists of definite proportion of zinc and copper,so it's compound
