Final answer:
A study that collects and analyzes results of multiple individual studies on a topic to identify patterns is called a meta-analysis.
Step-by-step explanation:
When multiple individual studies that are topic-relevant to each other are collected and analyzed to identify relationships and/or patterns across all findings, this type of study is known as A) A meta-analysis. A meta-analysis is a technique in which the results of virtually all previous studies on a specific subject are evaluated together. This method allows for a comprehensive synthesis of research findings, and while it may provide a broader understanding of a topic, it does not establish cause-and-effect relationships as it is correlational in nature.
