To determine which conditions allow the expression \( b > 5 \) to be true under the constraint that \( c > b > a \), let's analyze each option:

A. when \( a = -5 \) and \( c = 5 \)

  • Since \( c = 5 \) and \( a = -5 \), we need to find \( b \) such that \( -5 < b < 5 \).
  • Here, \( b \) can take values \( -4, -3, -2, -1, 0, 1, 2, 3, 4 \).
  • None of these values is greater than 5.
  • Not valid.

B. when \( a = 0 \) and \( c = 10 \)

  • Here \( 10 > b > 0 \).
  • Possible integer values for \( b \) can be \( 1, 2, 3, 4, 5, 6, 7, 8, 9 \).
  • All of these values are greater than 5.
  • Valid.

C. when \( a = 7 \) and \( c = 3 \)

  • This condition contradicts \( c > b > a \) because \( c = 3 < a = 7 \).
  • Not valid.

D. when \( a = 2 \) and \( c = 8 \)

  • Here \( 8 > b > 2 \).
  • Possible integer values for \( b \) can be \( 3, 4, 5, 6, 7 \).
  • Only \( 6 \) and \( 7 \) are greater than 5.
  • Valid.

E. Additional condition not specified.

Since there seems to be no specific condition given in option E, we cannot evaluate it.

Conclusion:

The valid options under the condition \( c > b > a \) and \( b > 5 \) are:

  • B (when \( a = 0 \) and \( c = 10 \))
  • D (when \( a = 2 \) and \( c = 8 \))

Thus, the answers are B and D.
