Rearrange the parts of the sentence in correct order.
It is the right to
P-who see us at our most vulnerable
Q-the indiscretions of doctors
R-privacy that protects us from

Let's evaluate the structural links from the introductory stem "It is the right to":
"Right to" is naturally completed by a noun or concept like privacy. Part R ("privacy that protects us from") continues this smoothly.

The preposition "from" in part R requires an object representing what we are being protected from. Part Q ("the indiscretions of doctors") acts as this object.

Part P ("who see us at our most vulnerable") uses the relative pronoun "who" to describe the preceding noun "doctors".

Thus, the proper sequential flow is RQP.
