science help PLS

Scientists earlier believed that the lowest measurable temperature is the freezing point of ice. However, modern scientists believe that temperatures below the freezing point of ice can also exist. What best accounts for these different opinions?

scientists propose contradictory ideas to include all possibilities

scientists come up with different hypotheses without enough evidence

scientists propose different ideas to avoid repetition of scientific knowledge

scientists having different interests may interpret the same data in different ways

im having trouble with this question pls help!

  1. I would choose a. It's a strange question, because we KNOW you can measure temperatures below zero C or 32 F.
