There are two main groups of monkeys, 'New World monkeys' and 'Old World monkeys. Monkeys in South and Central America are called as 'New World monkeys', whereas monkeys in Africa, Asia, and Europe are called as 'Old World monkeys'. New World monkeys include marmosets, capuchins, howler monkeys, squirrel monkeys, and spider monkeys. New World monkeys are arboreal, and some have long, slender limbs, that permit easy movement in the trees. A few have prehensile tails capable of wrapping around branches and serving as fifth limbs. Thus, the correct answer is option A.
