Thank you for the opportunity to help you with your question!

The answer is A.) 5,491,921.88

We use the compound interest formula :  A = P*(1 + (r/k))^(kt)

here k = 4  (compounded quarterly)

t = 5 years.

P = $4,200,000

Amount = $4,200,000*(1 + (0.054/4))^(4*5)

= $4,200,000*(1.0135)^20

= $4,200,000* 1.3076004476

= $5,491,921.88

Please let me know if you need any clarification. I'm always happy to answer your questions.
