The most human-readable way of formatting dates among the options given is 2017-03-10.

Here’s why:

1. 2017-03-10: This format is clear and unambiguous, making it easy to distinguish the year, month, and day. It follows the ISO 8601 standard, which is widely used and recognized internationally.

2. 2017/03/10: This format is also clear, but the use of slashes (/) can sometimes be mistaken for the US format (MM/DD/YYYY) or other regional variations.

3. 2017.03.10: Using dots (.) is less common and might be confusing for some people, as dots are often used in some countries to denote a different date format (e.g., DD.MM.YYYY).

4. 2017—03—10: Using em dashes (—) is unconventional for date formatting and can make the date harder to read or process at a glance.

Therefore, 2017-03-10 is the most straightforward and easily understood format for a wide audience.
