Answer : 2. "they collide less often"
Explanation :
In a semiconductor the mobility of electrons (referring to 'conduction electrons' or 'free-electrons') is greater than that of a holes (indirectly referring to 'valence electrons') because of different band structure and scattering mechanisms of these two carrier types
