The mode of a set of numbers is defined as the number that appears most frequently. In the number sequence \( 20123h7 \), we want the value of \( h \) such that the mode becomes 20.

First, we notice that the digit '20' contains two digits. In this sequence, since we're considering the mode as being 20, we must think of '20' as a possible combination of digits.

Since the other digits presented are \( 2, 0, 1, 3, 7 \), we do not initially have a '2' or a '0' that repeats, but we need to introduce '20' through selecting a suitable value for \( h \).

To have '20' appear as a mode, we can consider different possibilities for \( h \):

1. **If \( h = 2 \):** The sequence will be \( 2012327 \). Here, the digit '2' appears three times while the digit '1' and '0' appear only once. Thus, '2' would be the mode, not '20'.

2. **If \( h = 0 \):** The sequence will be \( 2012307 \). In this case, the digit '2' appears twice, '0' appears twice, and all other digits appear once. Thus, there is no mode '20'.

3. **If \( h = 1 \):** The sequence will be \( 2012317 \). Here, there are no repeating digits leading to '20' not being a mode.

4. **If \( h = 3 \):** The sequence becomes \( 2012337 \), where the digit '2' appears twice and thus would dominate, meaning '20' does not become a mode.

5. **If \( h = 7 \):** The sequence will be \( 2012377 \). The digit '2' appears twice, similar to before, leading to no mode of '20'.

From the options we considered, the most compelling choice comes from introducing '20' directly, and the only arrangement where '20’ could form is if 'h' was chosen to be any digit that would make '2' appear more than once along with a zero sufficiently so that '20' can be established as mode.

The conclusion indicates:
If we change `h` to a digit which ensures that ‘20’ itself is represented - such as treating `h` as a zero or aligning the pattern to ensure Y would fit.

Ultimately, just adjusting `h` itself shows that no individual digit alone cannot bring '20' up to mode, so there are no suitable digits.

If you'd like to reanalyze possible combinations of digits `h`, please consider:

The most promising choices appear where `h` repeats labels but derive up.

Thus finally, adjusting any entries of `h` alone to achieve the model of `20` which could be represented through several arrangements instead of selective digits.

Therefore, it can be established through further arrangements:
\( h = 2, 0 or combinations until `20` directly; therefore we'd fit as \( h = 20; thus h could be a contextual placement (Combining). \)
