I. 3574826<\/p>
II. 4857923<\/p>
III. 5986432 <\/p>
A. Both I and III<\/p>
B. Only II<\/p>
C. Both I and II<\/p>
D. Only I<\/p>
E. None of these<\/b><\/p>
Sol:<\/b><\/p>
From I: 3574826 \u2192 2465937 \u2192 2345679 (no digit remains unchanged) <\/p>
From II: 4857923 \u2192 5946832 \u2192 2345689 (no digit remains unchanged) <\/p>
From III: 5986432 \u2192 4897523 \u2192 2345789 (no digit remains unchanged) <\/p>
