Which statement can be used in lieu of access-list 5 permit 192.168.1.5 0.0.0.0?

The command access-list 5 permit host 192.168.1.5 specifies traffic coming from the host 192.168.1.5. The statement access-list 5 permit 192.168.1.5 0.0.0.0 achieves the same thing, as 0.0.0.0 means match all bits exactly. The 'host' keyword is the more readable alternative. The /24 notation is invalid in ACL syntax, and omitting the wildcard mask is also invalid syntax.
