Parents should cultivate in their children the habit of helping others.

The correct answer

To foster something means to encourage or promote its development. In this case, parents should encourage their children to help others. This can be done by setting a good example, talking about the importance of helping others, and providing opportunities for children to help out.

The other options are incorrect because they do not accurately reflect the meaning of the word “foster.”

• Propagate means to cause something to grow or spread. This is not the same as encouraging or promoting something.
• Sprout means to begin to grow or develop. This is not the same as encouraging or promoting something.
• Create means to bring something into existence. This is not the same as encouraging or promoting something.
