This question is missing the options. I've found the complete question online. It is the following:

Which statement about the authoritative child-rearing style is true?

a) authoritative parents exert control, yell, command, criticize, and threaten their children

b) many authoritative parents simply lack confidence in their ability to influence their child's behavior

c) authoritative parents combine low acceptance and involvement with little control and general indifference to issues of autonomy

d) authoritative parents insist on mature behavior, give reasons for their expectations, and use "teaching moments" to promote the child's self-regulation

The true statement is:

d) authoritative parents insist on mature behavior, give reasons for their expectations, and use "teaching moments" to promote the child's self-regulation

Explanation:

Even though it may sound strange at first, authoritative parenting style is considered the most successful one. Parents who present this style are often demanding. However, their demands tend to be reasonable, and they also offer their children the necessary resources to succeed. These parents have high expectations as well as high responsiveness to the children's emotional needs. They are also good at enforcing boundaries. They insist on mature behavior on their children's part and teach self-regulation.
