In the standard contradiction proof that

\sqrt{2}

is not rational, which initial assumption is made? a)

\sqrt{2}

can be written as

\dfrac{p}{q}

where

p

and

q

are odd integers. b) The decimal expansion of

\sqrt{2}

is terminating. c)

\sqrt{2}

can be written as

\dfrac{p}{q}

where

p

and

q

are coprime integers. d)

\sqrt{2}

can be written as

\dfrac{p}{q}
