____ is the determination of one or few constituents from the sample.

Correct option is A

Correct option: (a) Partial analysis
Why option (a) is correct:
· Partial analysis refers to the determination of one or a few specific constituents in a sample.
· It is commonly used when:
· Only selected parameters are required
· Time, cost, or purpose does not demand full composition analysis
❌ Why other options are incorrect
· (b) Complete analysis
· Involves determination of all or most constituents of a sample.
· (c) Proximate analysis
· Determines groups of components (e.g., moisture, ash, volatile matter).
· (d) Ultimate analysis
· Determines elemental composition (C, H, O, N, etc.).
�� Key Points
· Partial analysis → few constituents
· Complete analysis → total composition
· Widely used in soil, plant, and fertilizer analysis
✔️ Final Answer: (a)
