Step 1: Check M. F. Hussain.
M. F. Hussain is mainly known as a modern painter.
In this option set, he is counted among those not identified primarily as muralists.
So:
\[
A = \text{Not muralist in this list}
\]
Step 2: Check Jyothi Bhatt.
Jyothi Bhatt is known for painting, printmaking and photography.
He is not primarily listed as a muralist here.
So:
\[
B = \text{Not muralist}
\]
Step 3: Check Amrita Shergil.
Amrita Shergil is famous as a modern painter.
She is not known as a muralist.
So:
\[
C = \text{Not muralist}
\]
Step 4: Final conclusion.
The artists not counted as muralists in the given list are:
\[

\]
Hence:
\[
\boxed{\text{(A) A, B and C only}}
\]
