Some viruses contain both DNA and RNA as their genetic material is NOT true of viruses (option D).
<h3>What is a virus?</h3>
A virus is a non-living entity that needs a suitable host to reproduce its genetic material (DNA or RNA).
Viruses may contain a genetic material composed of other DNA or RNA but not both.
In conclusion, some viruses contain both DNA and RNA as their genetic material is NOT true of viruses (option D).

Answer:
Mintu should have chosen a material with a lower specific heat.
Explanation:
When we talk about specific heat, we refer to a specific quantity of heat that is needed for a substance or material to rise its temperature. In more concrete terms, is the amount of heat required for 1 gram of substance/material to elevate its temperature by 1 degree Celsius.
This would mean that a material with a high specific heat would require a higher quantity of heat to increase its temperature, so in this case, if Mintu wanted to make the heat transfer easier between the metal iron and the other piece of metal, he should have chosen a material that could elevate its temperature by receiving a lower quantity of heat, that is a material with a low specific heat. But instead he chose a metal with a higher specific heat, which will now make the heat transfer more difficult,and that was the error.
