Which of these materials is "hottest" in the sense that it is most likely to flow rather than to break (note that K stands for Kelvin, an absolute temperature scale in which zero is absolute zero and higher numbers mean warmer temperatures):

Group of answer choices

A material at 1001^oK that melts at 12000^oK.

All are the same temperature.

A material at 100^oK that melts at 200^oK.

A material at 250^oK that melts at 300^oK.

A material at 1000^oK that melts at 2000^oK.
