Hello!
Your answer is A, asthenosphere
<u>The asthenosphere is a part of the mantle</u>. It helps move the plates in the Earth.
It is <u>below the lithosphere,</u> between <u>80 and 200 km</u> below the surface.
Therfore, the asthenosphere is <u>the part of the mantle that is still a solid but flows like a thick, heavy liquid.</u>

Hope this helps!
Have a great day!
Answer:
2Al+ 6HNO3 ---- 3H2 + 2Al(NO3)3
Explanation:
Put coefficient a,b,c, and d for calculation:
a Al + b HNO3 = c H2 + d Al(NO3)3
for Al: a = d
for H: b = 2c
for N: b = 3d
for O: 3b = 9d
Suppose a=1, then d=1, b=3, c=3/2
multiply 2 to make all natural number, a=2, then b=6, c=3, d=2
