Decoding letters:

Letter A B C D
Stands for ÷ × + -

Given: 16 C 24 A 3 B 8 D 5 = ?

After interchanging the letters,

16 C 24 A 3 B 8 D 5 = ? ⇒ 16 + 24 ÷ 3 × 8 - 5 = ?

⇒ 16 + 24 ÷ 3 × 8 - 5 = ?

⇒ 16 + 8 × 8 - 5 = ?

⇒ 16 + 64 - 5 = ?

80 - 5 = ?

⇒ 75 = ?

Hence, "Option 3" is the correct answer.
