The sun is about 150 million km away from earth. the rays of sunlight that reach earth’s atmosphere are best represented as

Five

The diagram that represents rays from the sun is given below.

The answer from the diagram is parallel lines.

Six

The formula for this is n_i * Sin(i) = n_r * sin(r)

n1 = 1.333 water

n2 = 1.309 ice

i (angle) = 40o

r (angle) = ?

Solution

1.333 * sin(40) = 1.309*sin(r)

1.333 * sin(40)/1.309 = sin(r)

0.6546 = sin(r)

sin-1(0.6546)  = 40.88 degrees.

I guess my closest answer would be A. I'm not rounding at all and that's the answer I get.
