Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Option A is correct
![eduncle-logo-app]()
If the value of K is greater than 1, the products in the reaction are favored; if the value of K is less than 1, the reactants in the reaction are favored; if K is equal to 1, neither reactants nor products are favored
![eduncle-logo-app]()
In option in product side aromatic compound is formed..so product is favoured means K>1...so this is wrong
![eduncle-logo-app]()
In option B also product is favoured so K>1...as here cyclohepta trienyl cation is formed in product side which is aromatic
![eduncle-logo-app]()
In option A reactants side is favoured....as the hyperconjugation of CH3 is more than CD3...so reactant side carbocation is more stable than product side...so K<1..means less than unity...So this option is correct
![eduncle-logo-app]()
In option C also the product side is favourable as acetylide anion is more stable as negative charge is more stable in sp orbital...more s character...so K>1

got this shruti??

dueterated 3°C is less stable than undutersted 3° C so k less than 1 and cyclo heptatriene anion is less stable due to anti aromatic In this case also k is less than 1
