The ability of a child to stand and perhaps climb usually occurs around the age of months.
a. 12
b. 14
c. 10
d. 18

The answer is letter C.

Between months 9 and 10, babies have the ability to already move themselves around. Their curiosity to learn things is what drives them to experiment in their process of learning. During this stage the baby can already crawl and pull himself up in a standing position and he might be holding on to furniture sets to support this movement.  Towards the end of these months the baby may start to climb on things like stairs and foot stools.
