Minimum length of twine required by Paco to build a model ship = 3/8 yard = 0.375 yard. There are several options already given in the question. We have to check them before reaching a final conclusion. Option a = 3/10 yard = 0.3 yard So option is less than that reuired and hence cancelled. Option b = 1/4 yard = 0.25 So this option is also less than the length required and hence cancelled. Option c = 3/5 yard = 0.60 yard. This option looks feasible, but the final option needs to be checked before getting to the conclusion. Option d = 1/8 yard = 0.125 yard Now we can finally conclude that among all the options given in the question, option "c" is the correct option.
