The man first walks 30 km to the right, which means he is walking East.
Step 2: Evaluate the right turn.
He then takes a right turn. A right turn from East would direct him South.
Step 3: Evaluate the left turn.
After walking South, he takes a left turn. A left turn from South would direct him East.
Step 4: Conclusion.
Therefore, the man is now walking East. Thus, the correct answer is (3) East.
