A. Both will and revocable trust might make sense to you, here are two reasons:
Incapacity
A will only become effective when you die, what if you don't die but become incapable due to an accident?
A trust that includes an incapacity clause can help your family manage your affairs if that happens.
Disbursement
If you die with only a will, your heirs will likely need to get the will approved in a probate court before any assets disbursed, this could take time and money.
With a trust, the asset could be disbursed seamlessly when you die, according to what you have laid out in the trust.
