Which word does NOT belong with the others? tulip, rose, bud, daisy

Given data

• Word list: tulip, rose, bud, daisy.

Concept/Approach
Classify by type vs. growth stage. Three are specific flower species; one is a developmental stage of any flower.

Step-by-Step reasoning
Tulip – a kind of flowering plant. Rose – a kind of flowering plant. Daisy – a kind of flowering plant. Bud – an undeveloped flower stage; not a species.

Verification/Alternative
Replace species with others (lily, orchid) and the odd-one-out remains 'bud', confirming the rule.

Common pitfalls

• Thinking 'bud' is a type; it describes maturity, not taxonomy.

Final Answer
bud
