Final answer:
The answer is C. Tubular rivet, which is used in a manner similar to how a properly shaped peg fits into a matching hole in a children's toy, expanding to fill the hole and secure materials together. So, the correct option is C. Tubular rivet
Step-by-step explanation:
The correct answer to the question is C. Tubular rivet.
A tubular rivet is a type of fastener that is similar to a solid rivet, but it has a hollow shaft.
When installed, a tool pulls a mandrel through the rivet, expanding the shank's end to create a second head, which then holds materials together.
This process is akin to fitting a square peg into a square hole or a round peg into a round hole in a children's toy, where the peg has to be of the correct shape to fit through the hole.
Similarly, the tubular rivet, when compressed, will expand to fully fit and fill the hole.
Therefore, the correct option is C. Tubular rivet
