Final answer:
Blind rivets require access to just one side of the joint but are relatively weak.
Step-by-step explanation:
The correct answer is B. Blind.
Blind rivets are also known as pop rivets. They are used when you only have access to one side of the joint. This type of rivet is relatively weak compared to other types, such as solid or tubular rivets. Blind rivets work by inserting a rivet into a pre-drilled hole and then using a special tool to deform the rivet and create a strong connection.
