### 1. ### Break Down the Problem
To find Jane's age 4 years ago when we know her age in 3 years (𝑦 years), we need to express her current age and then subtract 4 years.

### 2. ### Relevant Concepts
Let’s denote:
- Jane's age in 3 years = 𝑦
- Jane's current age = 𝑦 - 3
- Age 4 years ago = Current age - 4

### 3. ### Analysis and Detail
1. **Calculate Current Age**:
Current age $ = 𝑦 - 3 $
2. **Calculate Age 4 Years Ago**:
Age 4 years ago $ = (𝑦 - 3) - 4 $
$ = 𝑦 - 3 - 4 $
$ = 𝑦 - 7 $

### 4. ### Verify and Summarize
We derived that Jane's age 4 years ago is represented by $ 𝑦 - 7 $. This aligns with option B.

### Final Answer
The correct answer is **B: $ 𝑦 - 7 $**.
