जर एका सांकेतिक भाषेत 'mxy das zci' म्हणजे 'good little frock'; 'Jmx cos zci' म्हणजे 'girl behaves good'; 'nug drs cos' म्हणजे 'girl makes mistake' आणि 'das ajp cos' म्हणजे 'little girl felt', तर त्या भाषेत 'frock' या शब्दासाठी कोणता शब्द संकेत आहे?

The correct answer is Option A (mxy).

Key Points:
• Comparing statement 1 ('mxy das zci' = 'good little frock') and statement 2 ('Jmx cos zci' = 'girl behaves good'): common word is 'good', code is 'zci'.
• Comparing statement 1 ('mxy das zci' = 'good little frock') and statement 4 ('das ajp cos' = 'little girl felt'): common word is 'little', code is 'das'.
• In statement 1, the remaining word is 'frock', and the remaining code is 'mxy'.
• Therefore, 'frock' = 'mxy'. Option 1 is correct.
• Key Takeaway: Isolate common words across sentences to find unique target code.
