Explanation:

To emphasize whom/what the action was done to, we need to use the passive voice. The original sentence is in the active voice (Cesar Diaz tied the balloons to the car door). The passive voice structure is 'object + be + past participle + by + subject'. The verb 'tied' is the past - tense form of 'tie', and its past participle is also 'tied'. Since the original sentence is in the past tense, we use 'was' as the helping verb.

Answer:

The balloons were tied to the car door by Cesar Diaz.
