Which pronoun best completes the sentence? how is the pronoun used? send gus and the details in an email.
a. me: direct object
b. me: indirect object
c. i: direct object
d. i: indirect object

Look at these individually:
Send me the details
Send I the details

Clearly, me is the correct choice. (me is an object, whereas I is a subject)

As for whether it is direct or indirect:
First, find our verb. (send)
A direct object answers the questions "What?" or "Whom?"
An indirect object answers the questions "To/for what?" or "To/for whom?"

The direct object is the details.
Send what? Send the details in an e-mail.

Me is an indirect object.
Send the details to whom? Send them to me.

*note* While "me" can answer the first question (send me in an e-mail) it does not make sense.

b. me: indirect object
