Researchers Measured Children's Fear of Unfamiliar Situations at 21 Months

Researchers measured children's fear of unfamiliar situations at 21 months and again at four years of age. When the children were brought back to the laboratory at five and a half years, the researchers found

A) that children who were inhibited earlier displayed more risky behavior when playing a ball-tossing game.
B) that children who were inhibited earlier displayed more risky behavior when playing on a mattress in a falling game.
C) that children who were inhibited at 21 months and four years again clung to their mother or father as before.
D) that children who were uninhibited at 21 months and four years began to cling to their mother or father at five and a half years.
