Please explain why option (1) is correct for the 44th question

Q44. The most stable carbocation amongst the following is

(1) $\underset{\oplus}{\nabla}$ (2) ${CH}_{2} = CH - \overset{\oplus}{C} H_{2}$

(3) CH₃ –CH₂ – $\overset{\oplus}{C}$ H₂ (3) CH₂ = C = $\overset{\oplus}{C}$ H

The solution is as follows:

1. The correct option is (1).

2. This is due to resonance. This is as shown below:

Please explain why option (1) is correct for the 44th question Q44. The most stable carbocation amongst the following is (1) ∇ ⊕ (2) CH 2 = CH – C ⊕ H 2 (3) CH3 –CH2 – C ⊕ H2 (3) CH2 = C = C ⊕ H
