FOR instrinsic semiconductor, what is the mobility of electron

a)300
b)1200
c)1800

i got this during a test
 

the mobility of holes is larger than the mobility of electrons

the mobility of Holes is in first line (µh)
the mobility of electrons is in second line (µe)

interinsic mobility dimension (cm2/V.s)
Ge \ Si \ GaAs
3900 \ 1500 \ 8600

1900 \ 450 \ 400
