Answer : The correct option is, (a) No. Potatoes will be warmer.

Explanation :

Formula used :

$Q=m\times c\times \Delta T$

where,

Q = heat taken

m = mass of substance

c = specific heat of substance = ?

$\Delta T$ = change in temperature

As we are given that the potatoes have a specific heat of $3430J/(kg^oC)$ and raisins have a specific heat of $1630J/(kg^oC)$ . That means higher the value of specific heat the more heat taken by the substance (more warmer will be the substance). So, the potatoes will be more warmer as compared to raisins.
