To solve this problem, we need to calculate the probability that a drawn ball is odd, given that the ball is less than 7.

### Step 1: Identify the relevant balls
The balls shown are numbered 1 through 10:
- Balls: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

### Step 2: List balls less than 7
The balls less than 7 are:
- 1, 2, 3, 4, 5, 6.

So, there are 6 balls in total that meet this condition.

### Step 3: Identify the odd balls among those less than 7
The odd numbers among these balls are:
- 1, 3, 5.

So, there are 3 odd balls.

### Step 4: Calculate the probability
The probability of drawing an odd ball, given that the ball is less than 7, is:
\[
\text{Probability} = \frac{\text{Number of odd balls}}{\text{Total number of balls less than 7}} = \frac{3}{6} = \frac{1}{2}.
\]

### Final Answer:
The correct answer is:
- **1/2**
