Hint 3 of 3
Trace each line with your finger and feel which one has the least up-and-down.
Show solution
Approach: the straightest path with the fewest wiggles is shortest
  1. Trace each marked line with your finger from the baby kangaroo to its mother.
  2. Every extra up-and-down wiggle makes a line longer, so the straightest line wins.
  3. Path A has the fewest wiggles, so it is the shortest. The answer is A.
