Examine figure 26-1 which area is the convection zonea. ab. bc. cd. d

B.   B

Explanation:

As we know that convective zone is that part of the sun where heat is primarily transferred by convection mode. In this part of sun major proportion is gas so that heat is transferred by gas molecules.

So here we will have

outer most part of the sun is E = CORONA

then it is the surface of sun which is A = PHOTO SPHERE

Then the inner part to the surface of sun is B = CONVECTIVE ZONE

then the next inner part is vacuum where heat is transfer by C = RADIATE ZONE

Then the innermost part of the sun is its D = CORE

so correct answer will be B

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
