The NASA personnel who were in charge of the Space Shuttle launch had clear evidence that freezing temperatures could pose a problem for the Shuttle, but they chose to ignore the evidence and proceeded with the launch anyway. The process that would BEST explain why the launch went ahead, even though there was evidence that indicated it should be delayed, is:

A. group polarization
B. groupthink
C. collectivism
D. reciprocity

Groupthink is the key factor behind the NASA personnel's decision to proceed with the Space Shuttle launches despite warning signs of possible problems.

Explanation:

Groupthink is the process that would best explain why the NASA personnel proceeded with the Space Shuttle launches despite clear evidence of potential issues. This phenomenon occurs when a group prioritizes consensus over critical thinking, leading to flawed decision-making. The Challenger disaster in 1986 and the Columbia tragedy in 2003 are examples of how groupthink can have catastrophic consequences.
