Correct answer: (A) A well-formulated hypothesis

Explanation

The indispensable element of good research is a well-formulated hypothesis.

A good supervisor helps but is not the essential core.

An adequate library is a support, not the sine qua non.

A large grant aids funding, not the intellectual essence.

The hypothesis directs the entire design and analysis.
