The right to livelihood is an _______ facet of the right to life, __________ as a fundamental right under the Constitution.
Step 1: The context is constitutional rights in India, particularly Article 21.
Step 2: Among the options:
- (a) "important, enjoying" → incorrect structure.
- (b) integral, guaranteed → correct, as livelihood is an integral part of life and is guaranteed under the Constitution.
- (c) "utmost, covered" → does not fit legal phrasing.
- (d) "ideal, procured" → contextually wrong.
Step 3: Hence, option (b) fits best. \[ \boxed{\text{integral, guaranteed}} \]
Test each pair by checking legal/constitutional collocation rather than plain meaning — Indian constitutional language typically pairs rights with words like "guaranteed," "conferred," or "enshrined."
Only option B fits both the descriptive sense of "facet" and the legal register expected for constitutional guarantees.
Hence, the correct answer is integral, guaranteed.
