Specific resistance of a conductor
depends upon
Dimension of the conductor
Composition of conductor material
Resistance of the conductor
Both (A) and (B)
Composition of conductor material
Specific
resistance or resistivity 
depend upon
temperature and composition of the conductor material
Hence, the correct option is (B).
&Key Points:-
Resistance depends upon the length (L), Area of cross-section (A), and
resistivity of material
