Step-by-Step Solution

Solution:

Step 1: Understand yield's dependency on blocks
Yield calls the block passed to the method; without a block, it has nothing to run.
Step 2: Recognize error cause
Calling yield without a block causes Ruby to raise LocalJumpError because it cannot jump to a block.
Final Answer:
Because yield expects a block to execute and none was provided -> Option A
