B

A - No Radioactivity (`""^(35)`S) detected in cells, B - Radioactivity (`""^(35)`S) detected in supernatant, C - Radioactivity (`""^(32)`P) detected in cells, D - No Radioactivity (`""^(32)`P) detected in supernatant

C

A - Radioactivity (`""^(35)`S) detected in cells, B - No Radioactivity (`""^(35)`S) detected in supernatant, C - Radioactivity (`""^(32)`P) detected in cells, D - No Radioactivity (`""^(32)`P) detected in supernatant

D
