In these kind of reactions, there is a transfer of electrons from one reactant to another. electrons are lost from one substance and gained by another.
Oxidation is loss of electrons from a substance, and Reduction is gain of electrons by a substance.
These two processes cannot occur without the other. If there is a reduction there must be an oxidation reaction and vice versa. The reactions usually occur simultaneously.
For example, table salt is formed by a redox reaction. Sodium is oxidized i.e. loses an electron (and becomes positively charged) while chlorine gas is reduced i.e. gains the electron (and become negatively charged). The result is formation of sodium chloride.
Answer: Option (c) is the correct answer.
Explanation:
A monomial is defined as an algebraic expression in which there is only one term present.
For example, 3x is a monomial.
A binomial is defined as an expression where there will be two terms present. For example, 
is a binomial.
A polynomial is defined as an algebraic expression which contains more than two terms.
For example, 
is a polynomial.
Thus, we can conclude that the given expression is a polynomial.
