To find the probability of choosing a diamond or a queen from a standard deck of 52 cards, we need to use the principle of inclusion-exclusion.

1. The probability of choosing a diamond (there are 13 diamonds in a deck) is:
\[
P(D) = \frac{13}{52}
\]

2. The probability of choosing a queen (there are 4 queens in a deck) is:
\[
P(Q) = \frac{4}{52}
\]

3. However, one of the queens is also a diamond (the queen of diamonds). Therefore, we must subtract the probability of choosing the queen of diamonds, which is:
\[
P(D \cap Q) = \frac{1}{52}
\]

Now, we apply the inclusion-exclusion principle:
\[
P(D \cup Q) = P(D) + P(Q) - P(D \cap Q)
\]
Substituting in our values:
\[
P(D \cup Q) = \frac{13}{52} + \frac{4}{52} - \frac{1}{52}
\]
Combining these fractions:
\[
P(D \cup Q) = \frac{13 + 4 - 1}{52} = \frac{16}{52} = \frac{4}{13}
\]

Therefore, the correct answer in the format you provided is:
\[
\frac{13}{52} + \frac{4}{52} - \frac{1}{52}
\]
This corresponds to the option:
**1352 + 452 − 152**.
