In which of the following sentences is the capitalized word or phrase used or placed incorrectly? a. ¿quién lo conoce á él? b. ¿quién conoce a maría? c. elena conoce a los dos. d. roberto conoce para maría y por alberto

Option D

Explanation: We need to see wich sentence is writen incorrectly.

Option a: ¿Quién lo conoce á ÉL?

This is written correctly.

Option b: ¿Quién conoce A MARÍA?

Here we replace the "El" for a name, "maria", this is written correctly.

Option C: Elena conoce A LOS DOS

Here again, the "subject" is at the end, si this is written correctly.

Option d: Roberto conoce PARA MARÍA Y POR ALBERTO

This is not written correctly, not only bad placed, so this is the right answer.

The right way to write this is:

Roberto conoce a María y a Alberto.

ok what are the questions?
