The planning of a school garden involves the proper spacing between plants to ensure their healthy growth. A group of 6th-grade students decides to plant 64 carrots in a straight line, leaving an exact space of 10 centimeters between each plant. However, they realize that the total length of the carrot line is not an exact multiple of one meter, the standard measurement they use to make markings in the garden. To solve this practical issue, the group decides to round the total measurement to the nearest meter in order to correctly plan the amount of material needed for the markings. Considering only the total length of the carrot line and the fixed spacing of 10 centimeters between them, what rounding technique should the students use and what could be the impact of incorrect rounding on the distribution of plants in the garden?

The students should round the spacing between plants to the nearest centimeter and keep the total length of the carrot line unchanged.

The rounding technique to be used by the students is decimal rounding to the nearest meter, with attention to the rounding rule. If the number of spaces between plants is fractional, the number should be rounded according to the standard rule: if the decimal part is less than 0.5, round down; if it is 0.5 or greater, round up.

The students should round the total number of plants to the nearest whole number, disregarding the total length of the carrot line.

It is necessary to round the total length of the carrot line to the nearest measurement unit, such as the nearest decameter (or deca).

Rounding should be done by the total number of spaces between plants, using the thousands' place rule to approximate to the nearest thousand.
