Concept- (1) Placing one coefficient in front of the chemical formula with the highest level of complexity and the other coefficient behind it. prior to anything else so that each atom is equal on both sides.
(2) Multiply each coefficient by the smallest number necessary to make them, if any fractional coefficients exist. In a reaction with a single fractional coefficient, the whole is frequently the denominator of the fractional coefficient.
We possess

There are two Na atoms on the LHS and one on the RHS.
NaCl's coefficient should be set to 2.
We get,

On both sides, we have an equal number of atoms for each element. Our equation is balanced as a result.
Hence, the correct answer is option (2).
