His ring and her digits

Question

A young lady named Thea decided to change the traditional codes and asked her boyfriend to marry her at the Eiffel Tower.

As he loves puzzles, she said while showing him this text, "rightly choose two consonants that appear twice in this puzzle, select the right digits among the following list and you'll get a present from me <3."

• 00
• 01
• 10
• 14
• 41
• 62
• 72

He found the right digits then received his wedding ring. How did he succeed?

Answer 1

I believe the correct digits are:

$0$ and $4$

Reasoning:

The puzzle places emphasis on the right column by using rightly and right. Additionally, I believe that the mention of Eiffel Tower and consommes are intentional. Consommes is a French word that translates consumes in English.

Using lateral-thinking, we can evaluate if any matching numbers in the right column, when added together (e.g. consume each other), create a new number. $0$ and $0$ result in zero, so they stay broken apart. $1$ and $1$ becomes $2$ while $2$ and $2$ become $4$. After this process, we're left with $0$, $0$, $2$, $4$ and $4$.

Out of these, only $0$ and $4$ occur twice.

_{Note: I intentionally didn't apply multiple passes, which would break this answer.}
