What size block shell should be used with a 4-inch manila line?
AI Explanation
The correct answer is B) 12".
The size of the block shell should be in proportion to the diameter of the line being used. For a 4-inch manila line, a 12-inch block shell would be the appropriate size. This is based on general industry standards and best practices for ensuring the block can properly accommodate and support the line without being too small or too large in comparison.
The other options are incorrect because an 8-inch block would be too small, a 16-inch block would be slightly oversized, and a 24-inch block would be excessively large for a 4-inch line.
