B) 6

D) 10

As children grow older, their social relationships and friendships become more complex and significant. By the age of 10, children have developed deeper emotional attachments to their friends and are more aware of the social dynamics around them. Losing a friend at this age can be particularly upsetting due to their increased capacity for emotional depth and the potential challenges in navigating the complexities of forming new friendships.
