The maximum length of the options field in an IPv4 header is 40 bytes. This is because the total length of the IPv4 header can be up to 60 bytes, and the minimum header length without options is 20 bytes. Therefore, the options field can occupy a maximum of 40 bytes (60 bytes total header length - 20 bytes minimum header length).
