According to Monkman and Grant, the relationship between the minimum creep rate and the rupture time is given as ________ (where the C and K are constant, and the tr is time to rupture and ε minimum creep rate).

• A. tr + Cε = K
• B. tr + C log ε = K
• C. log tr + C log ε = K
• D. tr + Cε = log K
• E. .a) tr + Cε = Kb) tr + C log ε = Kc) log tr + C log ε = Kd) tr + Cε = log K
