Step 1: Approach:
We find the one method that does not belong. The rest of the answer then follows by elimination.
Step 2: Find the odd one:

Step 3: Choose the option:
Speed play is C. So the answer must not contain C. Only option 2 has no C.
Final Answer:
\[\boxed{\text{Option 2: A, B and D only}}\]
