A closed-loop control system has a characteristic equation given by s3 + 2.4s2 + 1.8s + 0.5 = 0. Find out the value of a, b, c, and d using the Routh Hurwitz criterion.s311.8s22.40.5s1acs0bd

• A. a = 2, b = 0.5, c = 0, d = 1.3
• B. a = 0, b = 0, c = 0, d = 0
• C. a = 1.59, b = 0.5, c = 0, d = 0
• D. a = 4, b = 0, c = 9, d = 0.7
