The correct answer is 21.
To choose a team of 5 from a group of 7 climbers, you can use the combination formula:
nCr = n! / r!(n-r)!
where n is the total number of climbers (7) and r is the number of climbers you want to choose for the team (5).
So, 7C5 = 7! / 5!(7-5)!
= 7! / 5!2!
= (7 x 6 x 5 x 4 x 3) / (2 x 1)
= 21
Therefore, there are 21 different teams that can be formed.
