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.
