If R_T, R_h represent condition for reciprocity in case of transmission parameter and hybrid parameter respectively and similarly S_T, S_h represent condition for symmetry in case of transmission parameter and hybrid parameter respectively then match the following :
(1) R_T (a) A = D
(2) R_h (b) h₁₂ = h₂₁
(3) S_T (c) AD - BC = 1
(4) S_h (d) h₁₂ = - h₂₁
(e) B = c
(f) Δh = 1
