Answer:
Home
Step-by-step explanation:
When buying a smart speaker, you must be sure which voice assistant you would prefer. If you want to be connected with your Amazon account, then you can get Echo. If you prefer to be connected to your Google Account and want Google Assistant, then you would prefer Home. If you fancy Microsoft, you buy Cortana, and if you love Apple, you buy Homepod. Since Henry wants his smart speaker connected to his Google Account, then he has to buy the Google Home smart speaker.
