T_{A}

and

T_{B}

T_{A}

= (5/9)

T_{B}

T_{A}

= (3/7)

T_{B}

T_{A}

= (2/7)

T_{B}

T_{A}

= (4/7)

T_{B}

Answer : Option D
Explaination / Solution:

for any temperature scale

$\begin{aligned} \frac{X}{X_{T r}} = c o n s t . \\ \frac{T_{A}}{200} = \frac{T_{B}}{350} \\ T_{A} = \frac{4}{7} T_{B} \end{aligned}$
