<span>Penile shaft
</span>During erection, blood<span> flows into the spaces, causing distention and elevation of the penis. The amount of blood entering the penis can be increased by physical or psychological stimulation. As blood enters, there is a temporary reduction in the rate and volume of blood leaving the penis. The arteries carrying blood to the penis dilate; this, in turn, causes tissue expansion. The veins leading from the penis have funnel-shaped valves that reduce the outflow of blood. As the erectile tissue begins to enlarge, the additional pressure causes the veins to be squeezed against the surrounding fibrous tissue, and this further diminishes the outflow of blood. Essentially, blood becomes temporarily trapped in the organ.</span>

Options to this question were not provided. However, it is worthy to note that Mary Ainsworth's theory of mother-infant attachment classifies the relationship that children have with their caregivers as; Secure, Resistant, and Avoidant.
The Securely attached children are distressed when their mother is absent, they avoid strangers when their mother is not around but become friendly to strangers when their mothers are present.
They are also happy when their mother is around.
Generally, these sorts of children are confident and exhibit high self-esteem. So, Austin must have displayed some of these qualities.
