Hint: Most common site of fertilization so fertilization usually occurs in this widest section of fallopian tubes, narrow section of the fallopian tubes connecting this largest part to the uterine cavity, this segment has average length 5-8 cm and it is the site of ectopic implantation (pregnancy).

Complete answer:-
To answer this question you must know all about fallopian tubes.
Fallopian tubes are the important part of the female reproductive system, which connect the peritoneal cavity with fallopian (uterine) cavity, it provides the largest site for fertilization and also helps in the transportation of ovum from the ovaries to the body of the uterus.
Parts of fallopian tubes are as follow
INTRAMURAL (interstitial):- This part is located in the middle layer of the uterine wall of the uterus, it’s length is about 1 cm and width is about 0.7 mm. It's main function is to induce uterine contraction.
ISTHMUS:- It is the lateral continuation of the intramural part. It’s length is about 3 cm and width is between 1 and 5mm. It is a rounded and muscular part of the fallopian tubes.
AMPULLA:- It is the largest part of the fallopian tubes, most common site of fertilization, it is thin walled. Narrow section of the fallopian tubes connecting the ampulla to the uterine tubes. It has an average length of about 5-8 cm. It is a site of ectopic implantation(pregnancy).
INFUNDIBULUM:- It is the distal end of the fallopian tubes that has the finger-like projection referred as fimbriae, this project over the medial surface of ovaries.

Thus the largest part of the fallopian tube is ampulla.

fallopian tube play important role in egg transportation and fertilization, it named after 16th century by Italian anatomist Gabriele falloppio, fallopian tube is also known as oviduct or uterine tube, And ampulla is the part where the sperm are met and fertilization occurs.
