In germinating castor seeds,the $R.Q.$ is

When does the rate of respiration in plants change?

Refer to the given equation:
$2(C_{51}H_{98}O_{6}) + 145O_{2} \rightarrow 102CO_{2} + 98H_{2}O + \text{Energy}$
The respiratory quotient $(RQ)$ in this case is:

Given below are two statements.
$Statement-I$: When fat is the respiratory substrate, the $RQ$ is $1$.
$Statement-II$: When carbohydrate is the respiratory substrate, the $RQ$ is less than $1$.
In the light of above statements, choose the correct answer from the options given below.
