Step 1: Recall SAARC membership.
SAARC has eight states: Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.
Step 2: Compare with options.
Bhutan, Maldives, and Sri Lanka are members; Myanmar is not (it is an {ASEAN} member).
Step 3: Conclude.
\[
\boxed{\text{Myanmar (Option C) is not a SAARC member.}}
\]
