Explanation:

Here's a tip that might help you get through categorizing chemical reactions like this:

A combination reaction is when two or more reactants COMBINE to form a single product. This is also known as synthesis reaction. If you look a the chemical equation, it will have a form somewhat like this:

Reactant/s         Product

 A + B         →         AB

Taking your problem into consideration, letter c is a combination reaction because it started out as two reactants and combined to form one product.

P₄O₁₀ + 6H₂O      →   4H₃PO₄

  Reactants              Product

A decomposition reaction is when one reactant DECOMPOSES or breaks down into two or more products.

Reactant          Product

    AB         →        A + B

Your problem has 2 decomposition reactions, which are letters, a and e because if you notice, you have one reactant and it split into two products.

Fe₂(CO₃)     →       Fe₂O₃ + 2CO₂

Reactant               Product

2NaClO₃     →       2NaCl + 3O₂

Reactant               Product

A single displacement reaction is when one element or compound is displaced by another element or compound.

Reactants       Product

  AB + C     →    AC + B

                 or

  A + BC     →    AC + B

Your problem has letter d as your example of single-displacement.

2C + MnO₂ → Mn + 2CO₂

  A + BC     →  B   +   AC

Reactant           Product

A combustion reaction on the other hand occurs when hydrocarbons react with oxygen and heat. The product of a combustion reaction is ALWAYS carbon dioxide (CO₂) and water (H₂O).

        Reactants                        Product

Hydrocarbon   + O₂     →     CO₂    + H₂O

Lastly, your problem has letter b as an example of a combustion reaction. Notice that the product of the reaction is CO₂ and H₂O.

2C₆H₁₁OH  +   17O₂    →    12CO₂    + 6H₂O    

Hydrocarbon   + O₂     →     CO₂    + H₂O

answer; /// i do believe that the correct answer is (c)nuclear bond

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
