Answer: B, C, D
The ketone shown is 2-methylcyclohexanone. Kinetic enolate formation is irreversible and rate controlled; the bulky strong base LDA at −78∘C removes the more accessible C6 proton (statements 1 and 4). A weak base at 25∘C allows proton transfer between enolates, so the more substituted, more stable enolate predominates (statement 2). Statement 3 is false because kinetic control means rate, not stability, determines the product.
