Tardigrade Admin · Accepted Answer

Correct answer is (c) D → A → B → E → C

$A \to B \to C \to D \to E$

$E \to D \to C \to B \to A$

$D \to A \to B \to E \to C$

$C \to B \to E \to A \to D$

Correct answer is (c) $D \to A \to B \to E \to C$

A→B→C→D→E

E→D→C→B→A

D→A→B→E→C

C→B→E→A→D

Correct answer is (c) D→A→B→E→C

$A \to B \to C \to D \to E$

$E \to D \to C \to B \to A$

$D \to A \to B \to E \to C$

$C \to B \to E \to A \to D$
