Question

Amongst the Classimat faults A2, B1, D4, H2 and I1, the correct statement(s) is/are

• A. D4 and A2 are the thickest fault and the shortest fault, respectively
• B. I1 and H2 are the longest fault and the thinnest fault, respectively
• C. D4 and I1 are the thickest fault and the thinnest fault, respectively
• D. B1 and H2 are the most objectionable fault and the longest fault, respectively

Hint:

For Classimat codes, remember: the {letter} hints at the fault type/severity (thick vs thin), and the {index} tracks the length class—higher usually means longer.

Answer 1

The Correct Option is A, B

Step 1: Recall the Classimat coding idea.
Letters indicate the {type/degree} (e.g., thick vs thin) and the number/letter suffix indicates the {length class}. Larger index \(\Rightarrow\) longer fault; codes like D4 therefore denote very thick and very long, whereas indices like 1 or 2 denote short.
Step 2: Judge each option.
(A) D4 corresponds to a maximum-thick, long class; A2 denotes a short class among the group given. So D4 is the thickest and A2 the shortest \(\Rightarrow\) true.
(B) I1 lies in the highest length band in the set listed (longest), while H2 is a thin category among those given (thinnest) \(\Rightarrow\) true.
(C) Claims I1 is thinnest, which contradicts the coding; \(\Rightarrow\) false.
(D) Says B1 is the most objectionable and H2 the longest; neither matches the coding trends \(\Rightarrow\) false.
Final Answer: (A), (B)
