Dear student,

The single tertiary hydrogen "b" is nearly as susceptible as the six, primary "a" hydrogens, and almost doubly susceptible as any of the three, also-primary "d" hydrogens, illustrating the radical stability differences between tertiary and primary hydrogens.

To determine why a third dergree hydrogen is reactive we remove it.
A third degree hydrogen or tertiary hydrogen when removed will give us a tertiary carbocation.
A second degree hydrogen when removed will give us a seconday carbocation.
A first degree hydrogen or primary hydrogen when removed will give us a primary carbocation.
 
And a tertiary carbocation is favoured more as it is more stable than a secondary carbocation or a first degree carbocation thus, Third degree hydrogens are most reactive.
