Answer 1

The Correct Option is B

Step 1: Identify what hop flowers are. Hop flowers are obtained from the plant \textit{Humulus lupulus}. They contain resins and essential oils that impart bitterness, aroma, and preservative properties.
Step 2: Recall their industrial use. Hop flowers are widely used in the brewing industry:
They give beer its characteristic bitter taste.
They improve flavor and aroma.
They act as natural preservatives.
Step 3: Eliminate incorrect options.
Gluconic acid production — involves oxidation of glucose by bacteria.
Vinegar production — involves acetic acid bacteria.
Alcohol production — primarily carried out by yeast; hops are not used to produce alcohol.
Hence, the correct answer is \[ \boxed{\text{Beer production}} \]
