To speed up the malting process in brewing industry the growth hormone used is

Options

A. auxin
B. gibberellin
C. kinetin
D. ethylene

Explanation

To solve the question regarding which growth hormone is used to speed up the malting process in the brewing industry, we can follow these steps:

### Step 1: Understand the context of the question
The question relates to the brewing industry, which involves the production of alcoholic beverages. A key process in brewing is malting.

**Hint:** Consider what malting involves and its significance in brewing.

### Step 2: Define malting
Malting is the process where cereal grains, such as barley, are soaked in water, allowed to germinate, and then dried. This process converts the starches in the grains into sugars, which are essential for fermentation.

**Hint:** Think about the role of enzymes and sugars in the fermentation process.

### Step 3: Identify the hormones mentioned
The question provides four options: auxin, gibberellin, kinetin, and ethylene. We need to identify which of these hormones is specifically known to enhance the malting process.

**Hint:** Recall the functions of each hormone in plant growth and development.

### Step 4: Research the role of gibberellin
Gibberellin, also known as gibberellic acid, is a plant growth hormone that promotes stem elongation, seed germination, and flowering. It is particularly known for its role in breaking dormancy and promoting growth in seeds.

**Hint:** Consider how gibberellin might influence the malting process.

### Step 5: Conclude with the correct answer
Since gibberellin is known to speed up the malting process by promoting the germination of seeds and the activation of enzymes necessary for converting starches to sugars, it is the correct answer to the question.

**Final Answer:** The growth hormone used to speed up the malting process in the brewing industry is **gibberellin** (option 2).
