The correct answer is option (B) lemon juice.
pH refers to the logarithmic scale used to indicate the acidity or basicity of an aqueous solution. It is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less that 7 are considered acidic and the solutions with a pH greater that 7 are considered to be basic. A pH of 7 is neither an acid nor a base and is considered neutral.
An acid has a high concentration of hydrogen ions (H+) and a base has a low concentration of hydrogen ions. Higher the hydrogen ion concentration, pH is acidic. Among the given substances, lemon juice has a pH of 2, urine has a pH of 6, tomato juice has a pH of 4 and black coffee has a pH of 5. Since lemon juice has a pH of 2, it has the lowest –OH ion concentration.

Answer:
Explanation:
The sperm reproduction startes in the testicles.Sperm are produced in the testicles and develop to maturity while traveling from the seminiferous tubules through the epididymis into the vas deferens. As a male and female have sexual intercourse their are millions of sperms released which travel from the seminiferous tubules through the epididymis into the vas deferens as that happens the sperm enters throught the partner from here it takes its journey to the egg using ts tail to swim the first sperm to reaches the egg then uses the acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate the Ovum Coat of the Egg.It breaks through and forms a baby.
Hope this helps
