Answer:

value of a in terms of b and c is: $\mathbf{a=bc}$

Option D is correct.

Step-by-step explanation:

We are given:

$a=b^2c^2d \:and\: d=\frac{1}{a}$

We need to find a in terms of b and c

We have: $a=b^2c^2d$

Put value of d $d=\frac{1}{a}$

$a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc$

So, value of a in terms of b and c is: $\mathbf{a=bc}$

Option D is correct.
