DIRECTION: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
a. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
b. Both assertion (A) and reason (R) are true but reason \( (\mathrm{R}) \) is not the correct explanation of assertion (A).
c. Assertion (A) is true but reason (R) is false.
d. Assertion (A) is false but reason (R) is true
Assertion: In \( \triangle \mathrm{ABC}, \mathrm{DE} \| \mathrm{BC} \) such that \( \mathrm{AD}= \) \( (7 \mathrm{x}-4) \mathrm{cm}, \mathrm{AE}=(5 \mathrm{x}-2) \mathrm{cm}, \mathrm{DB}=(3 \mathrm{x}+4) \mathrm{cm} \) and \( \mathrm{EC}=3 \mathrm{x} \mathrm{cm} \) than \( \mathrm{x} \) equal to 4 .
Reason: Pythagoras theorem says that if a line is drawn parallel to one side of a triangle intersecting the other two sides, then the other two sides are divided in the same ratio.
