Which sentence uses an objective case pronoun as an indirect object?

I sent him an attachment that included photos of the picnic.

The indirect object him identifies to whom the action of the verb sent is performed.  

Wrong options:

I e-mailed him yesterday.

(The direct object him is the receiver of action within this sentence: I emailed him).

He wrote back to Bob and I with an answer to our questions.

(I is not an objective case pronoun; it should be "He wrote back to Bob and me...")

So, once again, the answer is the 2nd sentence (I sent him an attachment that included photos of the picnic.)

aye how much for a gram of crack my homie jeremy needs it he is a horn dog.

third person

explanation:

note the usage of names and pronouns, "james" & "the old man". this alone can confirm it as third person, as first person uses "i" and the like, while second person uses "you" and the like.
