• A)The mesons in A have a mean lifetime of 4.3 × 10^-8 s.
• B)The mesons in B have a mean lifetime of 3.6 × 10^-8 s.
• C)The mesons in both rockets have a mean lifetime of 2.6 × 10^-8 s.
• D)The mean lifetime of the mesons is the same for both rockets, but less than 2.6 × 10^-8 s.
• E)On average, the mesons in A will decay before the mesons in B.
