In a mixture of flammable vapor and air, if there is an excessive amount of vapor compared to the amount of air present, the mixture is referred to as "too rich." This means that there is a higher concentration of flammable vapor in the mixture than is required for it to ignite and sustain combustion.
In this situation, the concentration of vapor is so high that there is not enough oxygen available to support combustion. As a result, the mixture will not ignite, even if a source of ignition is present.
A too-rich mixture can be hazardous in certain circumstances because the concentration of flammable vapor can increase the risk of an explosion or fire. To minimize this risk, it's important to maintain the proper proportion of vapor and air in the mixture, so that combustion can occur safely.

Sir, The answer is wrong. It should be TOO Rich- option (a)
