Here are the answers to your questions:

340. The tube that carries the sperms out of the testes is the B. vas deferens.
The vas deferens transports sperm from the epididymis (which is attached to the testis) to the ejaculatory duct.

341. The process by which the sperms are released is called D. Ejaculation.
Ejaculation is the expulsion of semen, containing sperm, from the male reproductive tract.

342. The external genitalia in females is called C. vulva.
The vulva is the collective term for the external female reproductive organs.

343. Sterilisation in males is called as B. vasectomy.
A vasectomy involves cutting or tying the vas deferens to prevent sperm from being released.

344. Binary fission is seen in C. amoeba.
Amoeba, a single-celled organism, reproduces asexually through binary fission, where one cell divides into two identical daughter cells.

345. The endosperm nucleus is C. triploid.
In angiosperms, the endosperm is formed by the fusion of one sperm nucleus with two polar nuclei, resulting in a triploid (3n) nucleus.

346. The fertilization of human egg by the sperms takes place in B. Oviduct.
Fertilization typically occurs in the fallopian tube, also known as the oviduct.

347. Pollen tube contains B. two male nuclei.
In angiosperms, the pollen tube carries two male gametes (nuclei) to the embryo sac for double fertilization.

348. If the pollen is transferred to the stigma of the same flower, it is called B. Autogamy.
Autogamy is a type of self-pollination where pollen is transferred from the anther to the stigma of the same flower.
