Naturally, one expects that among disc galaxies, bulge SNe Ia should have highest contribution to the whole distribution of SNe Ia in S0–S0/a subsample, because among disc galaxies the ratio of bulge luminosity over disc luminosity (or B/D) is highest in the S0–S0/a subsample . In the case of Sa–Sm galaxies, both Type Ia and CC SNe dominate in the Sbc–Sc morphological bin (see Table \[table\_SN\_morph\]), where the B/D ratio is significantly lower than that in S0–S0/a galaxies . Moreover, the radial distributions of Type Ia and CC SNe in all the Sa–Sm subsamples can be drawn from the same parent distribution (see the $P$-values in Table \[diffSNe\_KS\_AD\]) supporting the fact that in
