  • A.only I is true
  • B.only II is true 
  • C.only III is true
  • D.I and III are true
  • E.None of these

Answer: A

Correct answer: This item cannot be worked as recorded

Translating the code: \(@\) is “greater than”, \(\#\) is “greater than or equal to”, \(\%\) is “less than or equal to”, \(*\) is “equal to” and \(\$\) is “less than”. The third statement is incomplete in this record: it reads “CP” with the symbol between C and P missing, and conclusion II has lost its symbol in the same way. That matters, because the two surviving statements give only \( R \ge D \) and \( D > C \), so \( R > C \); nothing links either letter to P without the lost symbol. Restoring it does not rescue the keyed answer either. If the missing symbol is \(@\), \(\#\) or \(*\), then \( C \ge P \), which gives \( R > P \) - conclusion I - but it also gives \( D > P \), which is conclusion III, so the answer would be “I and III are true”. If instead it is \(\$\) or \(\%\), then \( C \le P \) and neither conclusion is determined, so the answer would be “None of these”. No restoration makes I true while III is false, so “only I is true” is unreachable. The item needs its original symbols before it can be answered.
