Please try with below snippet. This should work.

choiceLabels: {
union(
union(
index(
rule!retrieveSubProgram(
"ABC",
"value from dd1"
).data,
"subProgram",
null
),
index(
rule!retrieveSubProgram(
"ABC",
"value from dd1"
).data,
"subProgram",
null
)
),
cast(
type!List,
"New Sub Program"
)
)
},
choiceValues: {
union(
union(
index(
rule!retrieveSubProgram(
"ABC",
"value from dd1"
).data,
"subProgram",
null
),
index(
rule!retrieveSubProgram(
"ABC",
"value from dd1"
).data,
"subProgram",
null
)
),
cast(
type!List,
"New Sub Program"
)
)
},

And you can try testing the specific expression rule by opening it in design mode and pass values(which will have row count as zero) to it.
