Jeppesen E(LO)1?

[Shubham1804]

Hey, i'm a student pilot and i was studying for my exam from the Oxford ATPL books. So in one of the map reading chapters, it says "Using the Jeppesen E(LO)1, pos 5211N 00931W, which denotes all following symbols?" with 4 answers to choose from.

Could someone please tell me what the E(LO)1 is and where can i find it?
