All of the following are true special predicates except.

A. A compound predicate is one that is passive.
B. A predicate can have direct or indirect object.
C.When a predicate is passive ,the subject is being acted upon rather an acting.
D. A predicate may consist of two or more verbs joined by and or or.
I know it not b or c.

I still maintain that B is a false statement. If there's an indirect object, there must also be a direct object.

To determine which of the given options is not true, we can eliminate the ones you already identified as true, which are option B and option C.

Option B states that a predicate can have a direct or indirect object, which is indeed true. A direct object is the noun or pronoun that receives the action of the verb directly, while an indirect object refers to the person or thing that indirectly receives the action.

Option C states that when a predicate is passive, the subject is being acted upon rather than acting. This is also correct. In a passive voice sentence, the subject is the one receiving the action, whereas in an active voice sentence, the subject is the one performing the action.

Now, let's evaluate the remaining options:

Option A: "A compound predicate is one that is passive."

A compound predicate refers to a predicate that consists of two or more verbs joined by a coordinating conjunction, such as "and" or "or." It does not necessarily have to be passive. For example:

- The lion roared and pounced. (compound predicate, active voice)

Therefore, option A is incorrect, as it wrongly states that a compound predicate is always passive.

Option D: "A predicate may consist of two or more verbs joined by 'and' or 'or'."

This option correctly defines a compound predicate, as explained above. It is true that a compound predicate can consist of multiple verbs joined by coordinating conjunctions.

Therefore, the incorrect option is A.
