Help!

[absana]

Hey guys.
I need a bit of help, this is more a techniques thing but yeah.
How would I play this here?
I would I be fingerpicking the two strings at the same time. Or strumming (whilst like resting a finger-left hand- on the muted string to mute it)?!
something else?
Thanks guys

Since you have an X (which means to mute the string) in between two other notes this would be strummed.

Without the X or an O it would be fingerpicked.
