Select the option in which the numbers share the same relationship as that shared by the given number-pair.

23 : 120

The logic here is

$$\left(23+1\right)\times5=24\times5=120$$ $$\longrightarrow\ $$ $$\left(\text{first number}+1\right)\times5=\text{second number}$$

Similarly,

$$\left(45+1\right)\times5=46\times5=230$$ $$\longrightarrow\ $$ $$\left(\text{first number}+1\right)\times5=\text{second number}$$

$$\therefore\ $$45 and 230 are related in the same way 23 and 120 are related.

Hence, the correct answer is Option D
