Which calculation computes the EIRP of an antenna?

Which calculation computes the EIRP of an antenna?
A . EIRP = Tx power (dBm) + Antenna Gain (dBi) – Cable Loss (dB)
B . EIRP= Cable Loss (dB) + Antenna Gain (dBi) – Tx power (dBm)
C . EIRP = Cable Loss (dB) + Antenna Gain (dBi) / Tx power (dBm)
D . EIRP = Tx power (dBm) + Antenna Gain (dBi) / Cable Loss (dB)
E . EIRP = Antenna Gain (dBi) – Cable Loss (dB) * Tx power (dBm)
F . EIRP = Tx power (dBm) * Antenna Gain (dBi) / Cable Loss (dB)
