Two options given here display the iambic meter.
A) is using the trochaic meter,
B) is using the anapestic meter,
but both C) and D) are using the iambic  meter!
I assume you need iambic pentameter  which is the option C). Hamlet's famous soliloquy is written in iambic pentameter, as is the case in most of Shakespeare's plays.
The option D) is using the iambic tetrameter however.
Hope this helps!
