Design a synthesis of 1-cyano-2-methylbicyclo[2.2.1]-2,5- heptadiene from cyclopentene and any other compounds using a diels-alder cycloaddition reaction. part 1 out of 9 choose the best option for the dienophile precursor to the target molecule.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

a corroding iron, if that's one of your choices
