(A) The given carbocation is a $1^{\circ}$ carbocation: $CH_3-CH(CH_3)-CH(CH_3)-CH_2^+$.Step $1$: $A$ $1,2-$ hydride shift occurs from the adjacent $2^{\circ}$ carbon to the $1^{\circ}$ carbocation,resulting in a more stable $2^{\circ}$ carbocation: $CH_3-CH(CH_3)-C^+(CH_3)-CH_3$.Step $2$: $A$ $1,2-$ methyl shift occurs from the adjacent $3^{\circ}$ carbon to the $2^{\circ}$ carbocation,resulting in the most stable $3^{\circ}$ carbocation: $CH_3-C^+(CH_3)-CH(CH_3)-CH_3$.Thus,a total of $2$ shifts ($1$ hydride shift and $1$ methyl shift) take place to reach the most stable carbocation.

How many $1,2-$ shifts take place in the following carbocation to reach the most stable form?
