<u>4NH3 + 5O2 → 4NO + 6H2O</u> is the correct balanced equation in the given chemical equation options.
What do you mean by Chemical equations?
A chemical equation is a written representation of the chemical reaction taking place between two or more substances. It can be written in words or symbols, and typically consists of the reactants (on the left side) and the products (on the right side). The arrow between them indicates the direction of the reaction.
The above equation is balanced because it has the same number of atoms of each element on both sides of the equation. The equation is balanced because it has 4 atoms of nitrogen (N) on the left side and 4 atoms of nitrogen on the right side. It has 5 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side. It also has 3 atoms of hydrogen (H) on the left side and 12 atoms of hydrogen on the right side.

They first 'cut out' genes using precise biological 'scissors' – restriction enzymes – and paste them into DNA from another organism like a bacterium or yeast where it is copied many thousands or millions of times. Molecular model of a restriction enzyme bound to DNA.
The continental plates collided, causing subduction to stop because India couldn't sink into the mantle, so instead it pushed the crust upward and downward, creating the Himilayas.
