Detailed Solution

Step 1: Analyze Statement I

Statement I states that ovulation is caused by an LH surge leading to the rupture of Graafian follicles. This is biologically accurate. The high concentration of Luteinizing Hormone (LH) in the blood, known as the LH surge, triggers the final maturation of the follicle and its subsequent rupture to release the secondary oocyte.

Step 2: Analyze Statement II

Statement II states that the remaining Graafian follicle transforms into the corpus luteum and secretes a large amount of estrogen. While it is true that the remaining follicular tissue transforms into the corpus luteum, the primary hormone secreted by the corpus luteum is progesterone, not estrogen. Although it secretes some estrogen, the defining characteristic of the corpus luteum is the secretion of large amounts of progesterone, which is essential for maintaining the endometrium.

Step 3: Conclusion

Since Statement I is correct and Statement II is incorrect due to the misidentification of the primary hormone, the correct option is (D).

Final Answer: Statement I is correct but Statement II is incorrect

A particle of mass M moves along a horizontal x axis from $x=0$ to $x=L$. The coefficient of kinetic friction varies as a function of x as $\mu_{k}(x)=\mu_{0}-\alpha x,$ where $\mu_0$, $\alpha$ are constants of appropriate dimensions, so that $\mu_{k}(L)=0$. The total work done by the frictional force during the motion is $n\mu_0 MgL$, where g is the acceleration due to gravity. The value of n is:
