The Gunners got the ball rolling on Friday by downing lower-league Coventry United, ahead of West Ham seeing off third-tier Ipswich.
Monday’s draw will match the capital trio up against Manchester City, who saw off Everton as they look to land a second domestic title after winning the Conti Cup.
Chelsea produced a superb second-half display to thrash Birmingham 5-0 at Kingsmeadow. The first-half was tight but last season's double winners did not look back after Magdalena Eriksson opened the scoring on the stroke of half-time.
Drew Spence doubled the lead before Beth England added a brace and Niamh Charles also got on the scoresheet. Jonna Andersson headed against the bar late on in a dominant showing.
City cruised through with Lauren Hemp twice on target in a 4-0 rout of Everton at the City Football Academy.
Hemp netted either side of half-time, first smashing in from close range and then flicking in at the near post from a corner, after Lucy Bronze had earlier hit the post.
Caroline Weir added a third with a brilliant long-range strike before Ellen White wrapped up the scoring in stoppage time.
A Lisa Evans effort proved the difference as the Hammers edged past National League Southern Premier Division leaders Ipswich 1-0. Evans struck in the 31st minute to settle a tight contest after Lucy Parker had earlier hit the bar for the Londoners.
