Which one of the following has the same value as `Delta_(f)H^(Theta), CO`?

Options

A. (a) `(1)/(2)Delta_(f)H^(Theta)(CO_(2))`
B. (b) `(1)/(2)Delta_(c)H^(Theta)("graphite")`
C. (c) `Delta_(f)H^(Theta) (CO_(2)) -Delta_(f)H^(Theta) ("graphite)"`
D. (d) `Delta_(c)H^(Theta) ("graphite") - Delta_(c)H^(Theta) (CO)`

Explanation

To solve the question "Which one of the following has the same value as ΔfH°(CO)?", we will analyze the options provided and determine which one corresponds to the standard enthalpy of formation of carbon monoxide (CO).

### Step-by-Step Solution:

1. **Understanding ΔfH°(CO)**:
The standard enthalpy of formation (ΔfH°) of a compound is defined as the change in enthalpy when one mole of the compound is formed from its elements in their standard states. For CO, the reaction can be written as:
\[
\text{C (graphite)} + \frac{1}{2} \text{O}_2 \rightarrow \text{CO}
