The options are wrong because if you read the questions carefully,they said that : How many minimum number of times he made 90 degree turns . The answer should be 1 because if he walks 5 blocks (excluding P) starting from P and then goes downwards only 2 blocks then he reaches point U by taking only one 90 degree turn.
