The energy of a system is given as E(t) = α^3 e^–βt, where t is the time and β = 0.3 s^-1. The errors in the measurement of α and t are 1.2% and 1.6%, respectively. At t = 5 s, maximum percentage error in the energy is : 

(1) 4% 

(2) 11.6% 

(3) 6% 

(4) 8.4%                                                 (JEE-2025)
