Is the 874251-001 built on ConnectX-4 or ConnectX-5?

Not confirmed by part number alone - this HPE model has shipped on both ConnectX-4 and ConnectX-5 silicon depending on production batch. T.E.S IT-SOLUTIONS reads the board marking before dispatch to confirm the exact generation.

Will T.E.S IT-SOLUTIONS confirm the exact silicon generation of 874251-001 before shipping?

Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, checks board marking and vendor data, before dispatch from EU stock.
