a. it is less expensive.

b. it produces better images of hard tissues.

c. it is faster.

d. it is safer.

Explanation:

• Option A: MRI is generally more expensive than CT, so A is incorrect.
• Option B: CT is better at imaging hard tissues (like bones), while MRI is better for soft tissues. So B is incorrect.
• Option C: CT scans are faster than MRI scans, so C is incorrect.
• Option D: MRI uses magnetic fields and radio waves, with no ionizing radiation, while CT uses X - rays (ionizing radiation). So MRI is safer in terms of radiation exposure.

Answer:

D. It is safer.
