What is laertes first question to claudius about his fathers death?

Let this be so.

His means of death, his obscure burial—

No trophy, sword, nor hatchment o'er his bones,

No noble rite nor formal ostentation,

Cry to be heard, as 'twere from heaven to earth,

That I must call't in question.

this would be in the imperative mood. it is a category of verb forms that are used to express orders,instructions,commands or requests.
