keywords: 

{'nanometer': [0, 0, 0, 1], '1ct3 cm': [0, 0, 0, 1], '1ct4 cm': [0, 0, 0, 1], 'cm': [2, 0, 7, 20], 'value': [0, 0, 1, 0]}

One nanometer is equal to 10^-7 cm.

Option 1: 10^-7 cm - This option correctly represents one nanometer. The negative exponent indicates that the value is a decimal fraction of a centimeter.

Option 2: 10^6 cm - This option represents one micrometer (also known as a micron), which is equal to one millionth of a meter, not one nanometer.

Option 3: 1CT4 cm - The "CT" in this option seems to be a typo or an unclear value. There is no recognized conversion factor that uses "CT" in relation to centimeters.

Option 4: 1CT3 cm - Similar to option 3, this option also includes the unclear value "CT" in relation to centimeters.

Overall, option 1 is the correct answer as it accurately represents the value of one nanometer. Alert - correct answer should be option 1.
