The answer is: The flowers in the garden bloom beautifully.
The verb <em>to be</em> can be conjugated as <em>am, is, are, was, were </em>or <em>been, </em>and it signifies to exist, occur o take place. In that respect, the chosen sentence does not possess the verb <em>to be</em> - it actually contains the verb <em>bloom</em>, which means to produce flowers.
The rest of the sentences are incorrect because all of them include conjugations of the verb to be, such as <em>is </em>and <em>was</em>.
