1.  Questions : How is 'DATE' written in the code language ?
Statements :

I.  DEAR is written as $ # @ ? in code in that code.
II. TREAT is written as % ? # @ % in that code.
III.TEAR is written as % # @ ? in that code.

A. Only I and II
B. Only II and III
C. All I, II and III
D. Only I and either II or III
E. None of these

Answer: Option D

Explanation:

Observing I, II and III, we find that similar letters have similar code symbols at the corresponding places in the code. So, this is direct-coding.

Thus, to find the code for DATE, we need the code for D which can be obtained from I only ( i. e. $ ) and the codes for A, T and E which can be obtained either from II or III @, # and % respectively).
