Two conductors have the same resistances at 0^(°) C but their temperature coefficients of resistance are α₁ and α₂. The respective temperature coefficients for their series and parallel combinations are:

(B) (α₁+α₂)/2, (α₁+α₂)/2

(A) α₁+α₂, (α₁ α₂)/(α₁+α₂)

(C) α₁+α₂, (α₁+α₂)/2

(D) (α₁+α₂)/2, α₁+α₂
