The subject "The baby" is third-person singular, so it requires the auxiliary verb "has". The present perfect continuous tense is formed with "has/have been + verb-ing", making "has been crying" the correct option.

"Lucas" is a singular subject, requiring "has" rather than "have". The present perfect continuous tense ("has been watching") is used here to describe an action that started in the past and is still continuing or has just finished, with a strong connection to the present.

"Children" is a plural noun, so it requires the plural auxiliary verb "have". Although the question lacks the standard subject-auxiliary inversion (which would be "have children been playing"), "have been playing" is the only option that is grammatically compatible with a plural subject in the present perfect continuous tense.
