Explanation:
Skeleton equations are also known as unbalanced equations.
Eg I react Oxygen, Hydrogen and Chlorine and I get Water and Chlorine Gas
H2 + Cl2 = HCl
Left Side
H = 2
Cl = 2
Right Side
H = 1
Cl = 1
As you can see it's not balanced is skeleton equation.

Answer: Option (B) is the correct answer.
Explanation:
When two circles are of same same then they are known as congruent circles.
Whereas a rectangle is a kind of parallelogram with all sides equal to 
.
Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.
Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.
