keywords: 

{'ultraviolet rays': [0, 0, 1, 0], 'velocity': [0, 2, 2, 6], 'magnetic field': [0, 0, 0, 6], 'aluminum': [0, 0, 1, 1]}

The correct answer is option 2: "1 only". Let`s analyze each statement to understand why.

Statement 1: "X-rays can pass through aluminum." This statement is correct. X-rays have high energy and short wavelengths, allowing them to penetrate most materials, including aluminum.

Statement 2: "X-rays can be deflected by a magnetic field." This statement is incorrect. X-rays are not affected by magnetic fields because they are neutral particles and do not have an electric charge. Only charged particles, such as electrons, can be deflected by magnetic fields.

Statement 3: "X-rays move with a velocity less than the velocity of ultraviolet rays in a vacuum." This statement is incorrect. X-rays, like all electromagnetic waves, including ultraviolet rays, travel at the speed of light in a vacuum, which is approximately 3 x 10^8 meters per second. Therefore, X-rays and ultraviolet rays have the same velocity in a vacuum.

In conclusion, only statement 1 is correct, while statements 2 and 3 are incorrect.
