Dear student, Option A that is red and green is correct because
safranin and fast green do not give other colors except red in
xylem and green in phloem Also safranin appears like a red colour
in chromosomes nucleus whereas fast green gives a bright green
color to cellulose cells and cytoplasm Thanks and regards
