Answer 2

Ιάκοβε, your answer is correct.  "Μπα" is an exclamation, common in oral speech.  One of its meanings is “nah”:

Θέλεις να έρθεις για φαγητό;

Μπα, δεν πεινάω. 

Would you like to come for lunch?

Nah, I am not hungry.

"Μπα;" (in a question) may also mean “really?”.  Here is an example where we express surprise and disbelief:

Η Μαρία πέρασε τις εξετάσεις.
Μπα, τι λές?  Αυτή δεν είχε διαβάσει ποτέ.

Maria passed the exams.
Really?  She never studied.
