Answer:
Options (3)=> the Curiosity rover detected carbon in organic molecules.
Step-by-step explanation:
The statement (1) and statement (3) are the most likely correct answers but since the question is likely to choose between one of the options(that is the options of 1 - 4), hence, there should be another options that will include options (1) and (3) in the question for us to be able to pick both options. But, since we are to pick one OPTION (3) WILL BE THE MOST CORRECT ANSWER.
So, you have been seeing " curiosity" all over in the question so what exactly is "curiosity''. Curiosity is a rover that is been use by the National Aeronautics and Space Administration(NASA) to enter the planet Mars since the year 2012.
THE REASON, OPTION (1) SHOULD NOT BE CONSIDERED IS THAT; Sulphur was said to be found in the John Klein rock and not its COMPOUND but sulphur itself.
