Question

why option one is correct??

Comments

I think option 1 is false, it states that if there is deadlock then either of the given condition holds. But we know all of the conditions must hold for deadlock to occur.

@adad20 Logically correct tho.
Now,

$ DL → (ME + HW + CW + NP) $
$ DL’ + (ME + HW + CW + NP) $

If DL is 1, ME,HW,CW,NP is 1, hence formula valid.
if DL is 0, DL’ is 1, and the formula is valid.
