Answer:
The colour in test tube A changes to brown because the starch gets broken down into disachharides in the presence of salivary amylase present in saliva, therefore it does not tests positive for starch and becomes brown.
Boy A is not correct since it's not orange and yellowish, it's brown. Please mark this as the brainliest if it helps!
