B. Case-Control
Explanation:
A case-control is a study that compares a group with an outcome of interest (cases) with a group who do not have the outcome (controls). This study aims to looks back retrospectively to compare how frequently the exposure to a risk factor is present in each group and with that to determine the relationship between that risk factor and the outcome.
So in this case, the cases are children with pervasive development disorder and the control is those without the disorders.
These studies are normally observational because no intervention is attempted.

In most cases, the general interpretive center and the speech center are located in the <u>left cerebral hemisphere.</u>
The left cerebral hemisphere, or a side of the brain, is responsible for speech and language, and because of this, it has also been called as the dominant hemisphere. The right hemisphere also plays a large part in interpreting or compiling spatial processing and the visual information.
Hemisphere in brain is one-half of the cerebrum, which controls muscle functions and also controls speech, thought, emotions, writing, reading, and learning. The left cerebral hemisphere controls muscles on the right side of the human body, and the right cerebral hemisphere controls muscles on the left side of the human body.
