The table above shows the maximum recorded life span of five animals. Removing which animal from the list will make the range of the remaining maximum life spans 66 years?

If the horse is removed, the maximum life span of the remaining animals would still include the whale, which has a significantly longer life span. This would not achieve a range of 66 years, as the difference between the new minimum and maximum values would still be too large.

Removing the orangutan would not create a range of 66 years either. This is because the remaining maximum life span would still include the whale, which would result in a larger difference than 66 years between the shortest and longest life spans.

If the tortoise is removed, the life span of the remaining animals would still reflect a considerable gap, especially with the inclusion of the whale. Thus, the range would exceed 66 years rather than fitting within that limit.

By removing the whale, the highest life span among the remaining animals would be lower. This would not condense the range to 66 years, as the remaining maximum span would still be much higher than the minimum life span.
