Question

Operating systems: which of the following scenarios guarantees deadlock free execution?

Comments

as an example for option b   suppose X is allocated d,c,e and Y has  a and Z has b.  SO no more resources can be given further and the system is in deadlock. similarly for option c and d you can find such a sequence leading to deadlock
