  • AEither statement alone is sufficient
  • BStatement I alone is sufficient but Statement II alone is not
  • CStatement II alone is sufficient but Statement I alone is not
  • DBoth statements together are needed (neither alone is sufficient)

Step-by-Step Solution

I leaves the eastward leg unknown; II gives only that leg (3 m). Together the legs are 4 m and 3 m, so the shortest distance is the square root of (16+9) = 5 m.
Answer: D) Both statements together are needed (neither alone is sufficient)
