Answer:
Golf team - Tigers
Explanation:
Diving team = Hornets
Hornets are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellow jackets. Some species can reach up to 5.5 cm (2.2 in)
Since the soccer team's nickname is not the Tigers, then there's only the 'Bear' option left
=> Soccer team = Bear
At the end, there's still one option left; Tigers
Therefore, the nickname of the golf team is Tigers
