Concept:
In Vedic philosophy, human beings are said to be born with certain debts or Rnas.
These debts are duties toward gods, sages and ancestors.
Step 1: Identify Deva Rna.
Deva Rna means debt toward gods.
So:
\[
B = \text{Correct}
\]
Step 2: Identify Rishi Rna.
Rishi Rna means debt toward sages or seers.
So:
\[
C = \text{Correct}
\]
Step 3: Identify Pitra Rna.
Pitra Rna means debt toward ancestors.
So:
\[
E = \text{Correct}
\]
Step 4: Eliminate other options.
Matra Rna and Prakriti Rna are not counted among the standard Vedic debts in this question.
So:
\[
A,\ D = \text{Incorrect}
\]
Therefore, the correct Rnas are:
\[
B,\ C,\ E
\]
Hence:
\[
\boxed{\text{(D) B, C and E only}}
\]
