Which response uses the correct technical wording for this situation? Context: split-ring motor kit evidence. Learning objective: (Physics only) (HT only) Identify np and ns as the number of turns on the primary and secondary coils.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): split-ring motor kit evidence shows (Physics only) (HT only) Identify np and ns as the number of turns on the primary and secondary coils. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): split-ring motor kit evidence shows (Physics only) (HT only) Identify np and ns as the number of turns on the primary and secondary coils. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Transformers (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The split-ring motor kit evidence detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
