B. Bacteria
C. Algae
D. None of the above

Answer 1

Hint:- Abortion is the termination of a pregnancy by either removal or expulsion of the fetus. An abortion that occurs without any human intervention is called miscarriage or spontaneous abortion. When deliberate steps are taken by clinicians and parents to end a pregnancy it is called induced abortion.

Complete answer:-
Bacteria can cause problems resulting in a miscarriage. The two most common are Mycoplasma hominis and Ureaplasma urealyticum. They are usually known to live in the genital tracts of healthy men and women but act as a risk factor of miscarriage. Infection caused by these bacteria causes the endometrial lining to inflame, thus the embryo can’t develop further which leads to abortion.
Infection of mycoplasmas in the maternal genital tract during early gestation or preconception is associated with spontaneous abortion, and perinatal morbidity and mortality. To prevent adverse pregnancy outcomes in women and fetuses routine screening and treatment for the underlying condition are recommended.
Ureaplasma urealyticum colonizes the women's genital tract. It is associated with premature rupture, preterm birth, and spontaneous abortion. Ureaplasma parvum is found in the placenta and endometrium and is associated with stillbirth and spontaneous miscarriage and lowers than normal weight of the infant. Ureaplasma parvum can also penetrate amnion in the second trimester and cause chorioamnionitis.
Thus, the right option is B.

Note:- Listeriosis, is also a common bacterial infection that increases the risk of preterm labor or miscarriage, and stillbirth the Newborns may be asymptomatic but may develop the delayed infection after several weeks after birth.
