एका संकेत प्रणालीनुसार, 'bright fresh sunny day' चा संकेत 'mec rig koh muf' हा आहे. 'fragrance of fresh flowers' चा संकेत 'rig pok og hez' हा आहे. 'bright colours of baskets' चा संकेत 'net muf nuk pok' हा आहे आणि 'basket filled with flowers' चा संकेत 'pit net og jec' हा आहे. या माहितीचा उपयोग करून पूर्णपणे विसंकेतित न करता येणारा शब्द गट निवडा.

The correct answer is Option D (bright flowers filled baskets).

Key Points:
• Code Elimination Step-by-Step:
• 1. Comparing (1) & (2): common word is fresh = rig.
• 2. Comparing (1) & (3): common word is bright = muf.
• 3. Comparing (2) & (3): common word is of = pok.
• 4. In sentence 2: words left are fragrance, flowers and codes og, hez.
• Comparing with (4) ('basket filled with flowers' = 'pit net og jec'): common word is flowers = og.
• Therefore, fragrance = hez.
• 5. In sentence 3: colours, baskets have codes net, nuk. Sentence 4 has 'basket' matching net.
• Thus, basket/baskets = net, and colours = nuk.
• 6. In sentence 4: 'filled with' have codes pit, jec (cannot distinguish 'filled' from 'with').
• 7. Therefore, in option 4: 'bright flowers filled baskets', the word filled cannot be uniquely decoded between 'pit' and 'jec'.
• Hence, option 4 cannot be coded/decoded completely.
• Key Takeaway: 'Filled' cannot be isolated between 'pit' and 'jec', making group 4 incomplete.
