Which is correct

Options

A. Humans show spontaneous ovulation
B. Several enzymes occur in bile juice
C. Monkeys, apes and humans have estrus cycle
D. Urine is pale yellow and slightly alkaline.

Answer

To determine which statement is correct among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Option A: "Human shows spontaneous ovulation."**
- Spontaneous ovulation refers to the regular release of an ovum (egg) during the menstrual cycle, regardless of whether fertilization occurs.
- In humans, ovulation occurs approximately once a month as part of the menstrual cycle. Therefore, this statement is correct.

2. **Analyze Option B: "Several enzymes occur in biojewels."**
- The term "biojewels" seems to be a typographical error or misinterpretation. If it refers to "biomolecules," we need to clarify that biomolecules can contain enzymes. However, if it refers to something else, we need to consider that.
- Assuming it refers to a biological context, enzymes are indeed present in various biological systems, making this statement misleading or incorrect.

3. **Analyze Option C: "Monkeys, apes, and humans have Easter cycle and the urine is pale and slightly alkaline."**
- The term "Easter cycle" appears to be a typographical error for "estrous cycle." The estrous cycle is different from the menstrual cycle.
- Monkeys and apes have a menstrual cycle similar to humans, not an estrous cycle. Therefore, this statement is incorrect.
- Additionally, urine in humans is typically pale yellow and slightly alkaline due to bicarbonate ions, which is true, but the context of the cycle is incorrect.

### Conclusion:
After analyzing all options, the correct answer is **Option A: "Human shows spontaneous ovulation."**
