Answer 1

The correct option is A

B, E, F, A and C

$\begin{array}{ccc}& \text{Reaction Names}& \text{Reactions}\\ i)& \text{Displacement Reaction(element displacing}& B.)Fe+Pb(N{O}_3{)}_2\to Fe(N{O}_3{)}_2+Pb\\ & \text{other element from its compound)}& \\ ii)& \text{Decomposition Reaction(single product}& D.)KCl{O}_3\to 2KCl+3O_2\\ & \text{decomposing into two or more than two products)}& \\ iii)& \text{Redox Reaction(both oxidising and reducing)}& E.)C{O}_2+H_2\to 2CO+H_{2}O\\ iv)& \text{Combination Reaction(two reactants combine}& A.)CaO+O_2\to 2Ca(OH{)}_2\\ & \text{to give a single product)}& \\ v)& \text{Double Displacement Reaction(exchange of}& C.)MgC{l}_2+Ca(OH{)}_2\to Mg(OH{)}_2+CaC{l}_2\\ & \text{ions between reactions)}& \end{array}$
