I would say that the answer is d?
Explanation:
Given that,
The frequency of electromagnetic spectrum is 
(A) Let the wavelength of this radiation is
. We know that,

So, the wavelength of this radiation is
.
(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

h is Planck's constant

1 kcal = 4184 J
It means,

Hence, this is the required solution.

Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, the compound C₆H₁₄ is hexane. Hexane is a member of saturated hydrocarbons (homologous series) called alkanes (with the general formula CₙH₂ₙ₊₂). The structure for an hexane is shown below
H H H H H H
I I I I I I
H - C - C - C - C - C - C - H
I I I I I I
H H H H H H
which can also be written as
CH₃CH₂CH₂CH₂CH₂CH₃
It seems like the answer is C, you really just need to use the process of elimination.
