Assertion : Mobilisation of stored food in germinating seeds is triggered by gibberellins.
Reason: In embryo of seed, gibberellins are produced during seed germination.

Options

A. If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.
B. If both Assertion and Reason are true but the Reason is not a correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason about gibberellins in germinating seeds, we can break it down into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Mobilisation of stored food in germinating seeds is triggered by gibberellins."
- Gibberellins are plant hormones that play a crucial role in various growth processes, including seed germination.

### Step 2: Understand the Reason
The reason states that "In the embryo of the seed, gibberellins are produced during seed germination."
- During seed germination, the embryo indeed produces gibberellins, which are responsible for initiating the mobilization of stored food.

### Step 3: Analyze the Relationship Between Assertion and Reason
- The assertion is true because gibberellins do trigger the mobilization of stored food.
- The reason is also true because gibberellins are produced in the embryo during germination.

### Step 4: Determine the Correctness of the Reason as an Explanation of the Assertion
- The reason correctly explains the assertion since the production of gibberellins in the embryo leads to the mobilization of stored food.

### Step 5: Choose the Correct Option
Based on the analysis:
- Both the assertion and reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct option is the first one.

### Final Answer
Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
