Final answer:
To determine the reason for disqualification in a t-test, which involves agility, one must refer to specific test guidelines. Disqualifying actions often relate to incorrect movements or techniques, such as shuffling or crossing feet, against the stated rules.
Step-by-step explanation:
The t-test is a physical fitness test used to measure a student's agility, balance, and coordination. In the context of this question, the t-test seems to involve running between a series of cones set up in a 'T' configuration. The reasons for disqualification in a t-test typically include technical errors that go against the rules of the test. However, without the full context, it's difficult to determine the correct rules for this specific t-test. Typically, in agility tests:
- A) Touching the base of cone D might disqualify you if it indicates an incorrect turn or pivot.
- B) Shuffling from cone C to D could be a reason for disqualification if the rules state that you should run and not shuffle.
- C) Crossing the feet from cone B to C might be against the rules if they specify that you should not cross your feet.
- D) Running forward from cone A to B is usually a part of the test and not a reason for disqualification.
Without specific instructions associated with this t-test, it's important to refer to the guidelines given during the test to understand which actions are permitted or grounds for disqualification.
