Option 1: 9.46 x 10-15 m

This option is incorrect. The value provided is too small. A light year is a unit of distance and is much larger than this value.

Option 2: 9.46 x 1015 m

This option is correct. A light year is defined as the distance that light travels in one year in a vacuum. The speed of light is approximately 3 x 108 meters per second. By multiplying the speed of light by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds), we can calculate that one light year is approximately equal to 9.46 x 1015 meters.

Option 3: 9.46 x 10-13 m

This option is incorrect. The value provided is too small. It is closer to the value of one light month rather than one light year.

Option 4: 9.46 x 1013 m

This option is incorrect. The value provided is too small. It is closer to the value of one light decade rather than one light year.

In conclusion, option 2, 9.46 x 1015 m, is the correct answer as it accurately represents
