To solve the expression 25 C 21 D 7 B 3 A 4, follow these steps:

- Replace C with -, thus 25 C 21 becomes 25 - 21.

- Replace D with ÷, thus 21 D 7 becomes 21 ÷ 7.

- Replace B with ×, thus 7 B 3 becomes 7 × 3.

- Replace A with +, thus 3 A 4 becomes 3 + 4.

Now, evaluate the expression with proper order of operations (BODMAS/BIDMAS):

1. Division first:

21 ÷ 7 = 3

2. Multiplication next:

3 × 3 = 9

3. Subtraction next:

25 - 9 = 16

4. Addition last:

16 + 4 = 20

Among the given options, Option 1: 20 is correct.

Therefore, correct Answer is: Option 1: 20
