because of the "likely" in the question, I would say C (three years old)
but this question is very subjective. Children have their own progresses and can't be compared.....
Some are walking at 12 months, some at eighteen months, same for speaking !
Weak bones, tripping, poor foot placement, poor eye coordination, drowsiness, ect.
Myopia is best described as having no imagination, foresight and nearsightedness.
They should be kept in all of the above
B i would say because with a voice blind people may not know what to do in case it broke. idk if this helps
