The equation is solved with the help of the BODMAS Rule:
Let's check each option one by one.
Option 1) -, ÷, ×, =
⇒ 23 - 2 ÷ 2 × 5 = 18
⇒ 23 - 1 × 5 = 18
⇒ 23 - 5 = 18
⇒ 18 = 18
⇒ LHS = RHS
Option 2) -, ÷, +, =
⇒ 23 - 2 ÷ 2 + 5 = 18
⇒ 23 - 1 + 5 = 18
⇒ 28 - 1 = 18
⇒ 27 ≠ 18
⇒ LHS ≠ RHS
Option 3) -, ÷, =, +
⇒ 23 - 2 ÷ 2 = 5 + 18
⇒ 23 - 1 = 5 + 18
⇒ 22 ≠ 23
⇒ LHS ≠ RHS
Option 4) -, ×, ÷, =
⇒ 23 - 2 × 2 ÷ 5 = 18
⇒ 23 - 2 × 0.4 = 18
⇒ 23 - 0.8 = 18
⇒ 22.2 ≠ 18
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 1".
