When referring to both natural and non-natural persons (i.e. organisations) at the same time, is it appropriate to use 'which' or 'who'?
For example:
1.
- '... request the person or body who has the responsibility for this task..' or
- '... request the person or body which has the responsibility for this task..'
2.
- '...the person or body to whom the application was directed' or
- '...the person or body to which the application was directed'
(There is a reason that 'person' precedes 'the body')
