To determine the correct inequality representing the number of candles Mark could buy, we need to identify how many additional candles he needs after accounting for the 2 candles he already has.

Mark needs a total of at least 7 candles for the party. Since he already has 2 candles, the number of candles he needs to buy (let's represent that number as \( x \)) must satisfy the following inequality:

\[
2 + x \geq 7
\]

To isolate \( x \), we can rearrange this inequality:

1. Subtract 2 from both sides:
\[
x \geq 7 - 2
\]
\[
x \geq 5
\]

So, the correct inequality that represents the number of candles Mark could buy is:

\[
x \geq 5
\]

Looking at the provided options, the correct choice is:

**None of the choices given reflects this accurate needed inequality. However, if we consider the closest relation, \( x + 2 \geq 7 \) similarly results in \( x \geq 5\). Thus, the best answer from the options provided is:**

**\( x + 2 \geq 7 \)**
