In plain English
FAR 52.217-3, Evaluation Exclusive of Options, is a solicitation provision prescribed at FAR 17.208(a), most recently dated Apr 1984. The complete official text is reproduced below, verbatim, from GSA's published FAR source files.
Its text contains no sentence requiring insertion into subcontracts; see the flowdown section below for what that does and does not mean.
Does it flow down to subcontracts?
No flowdown mandate found in the clause text
This is a solicitation provision — it applies to offerors when submitting an offer, not to contract performance, so subcontract flowdown is generally not the operative question for it.
Where it's prescribed
As prescribed in 17.208(a), insert a provision substantially the same as in the following in solicitations when the solicitation includes an option clause and does not include one of the provisions prescribed in 17.208 (b) or (c):
Prescribing reference: FAR 17.208(a), FAR 17.208.
