2) H, J, L, K, M, O
3) H, J, K, M, L, O
4) H, J, L, M, K, O

Answer 1

Based on the given restrictions, options 2) H, J, L, K, M, O and 4) H, J, L, M, K, O could be the order in which the lawyers speak.

Step-by-step explanation:

Based on the given restrictions, K and L must speak consecutively and O must speak fifth. Let's analyze each option:

1. H, J, K, L, M, O: This order does not follow the restriction that K and L must speak consecutively, so it is not a valid option.
2. H, J, L, K, M, O: This order follows the restriction that K and L must speak consecutively, and O speaks fifth. It is a valid option.
3. H, J, K, M, L, O: This order does not follow the restriction that K and L must speak consecutively, so it is not a valid option.
4. H, J, L, M, K, O: This order follows the restriction that K and L must speak consecutively, and O speaks fifth. It is a valid option.

Therefore, the valid options are 2) H, J, L, K, M, O and 4) H, J, L, M, K, O.
