Concept:
In logic, terms have:
\[
\text{Denotation}
\]
and
\[
\text{Connotation}
\]
Denotation means the objects or individuals to which a term applies.
Connotation means the qualities or attributes suggested by a term.
Step 1: Check proper names.
Amartya Sen and John Rawls are proper names.
They mainly denote particular individuals.
So:
\[
A,\ D = \text{Not connotation}
\]
Step 2: Check Rationality.
Rationality is a quality or attribute.
So:
\[
B = \text{Connotation}
\]
Step 3: Check Educated.
Educated also expresses an attribute or quality.
So:
\[
C = \text{Connotation}
\]
Step 4: Final conclusion.
The connotative terms are:
\[
B,\ C
\]
Hence:
\[
\boxed{\text{(C) B and C only}}
\]
