It seems like the question is asking for the ratio between the side length \(a\) of an equilateral triangle and its height \(h\). Let's solve this step by step.

### Step 1: Formula for the height of an equilateral triangle
For an equilateral triangle with side length \( a \), the height \( h \) can be given by:

\[
h = \frac{\sqrt{3}}{2} a
\]

### Step 2: Find the ratio \( \frac{a}{h} \)
We need to find the ratio of the side length \(a\) to the height \(h\):

\[
\frac{a}{h} = \frac{a}{\frac{\sqrt{3}}{2} a} = \frac{a \times 2}{a \times \sqrt{3}} = \frac{2}{\sqrt{3}}
\]

### Step 3: Simplify the ratio
To simplify \( \frac{2}{\sqrt{3}} \), we multiply the numerator and denominator by \( \sqrt{3} \) to rationalize the denominator:

\[
\frac{2}{\sqrt{3}} = \frac{2 \times \sqrt{3}}{3} = \frac{2\sqrt{3}}{3}
\]

### Step 4: Interpret the result in terms of the options given
The simplified ratio \( \frac{2\sqrt{3}}{3} \) does not directly match the options provided. However, the options might be written differently, possibly due to a misprint or error. None of the provided options seem to directly correspond to the correct ratio, but if there's a minor printing error, (D) \( 2:43 \) might be a misrepresentation of \( \frac{2\sqrt{3}}{3} \).

### Conclusion:
Given the correct formula and simplification, the expected ratio of the side length to height should be \( \frac{2\sqrt{3}}{3} \). Since none of the options match this exactly, this might indicate an issue with the options given in the question.

Do you have any questions or need further clarification?
