Match List-I (Scientists) with List-II (Well known as) and select the correct answer using the codes given below the lists:

List-I (Scientists)	List-II (Well known as)
A. Birbal Sahni	1. Mathematician
B. Ramanujan Srinivasa	2. Paleobotanist
C. Sir C.V. Raman	3. Physicist-Botanist
D. Sir J.C. Bose	4. Physicist

Codes:

	A	B	C	D
(a)	3	1	4	2
(b)	2	1	4	3
(c)	3	4	1	2
(d)	2	4	1	3

The matching of scientists to their respective fields is as follows: Birbal Sahni was a renowned Indian paleobotanist who founded the Birbal Sahni Institute of Palaeobotany and specialized in fossil plants [t1][t3][t4]. Srinivasa Ramanujan was a legendary mathematician known for his contributions to number theory and mathematical analysis [t4][t7][t9]. Sir C.V. Raman was a Nobel Prize-winning physicist famous for the Raman Effect [t4][t7]. Sir J.C. Bose was a polymath who excelled as both a physicist and a botanist, pioneering research in radio waves and plant physiology using the crescograph [t2][t5][t6][t8]. Therefore, the correct sequence is Birbal Sahni (Paleobotanist - 2), Srinivasa Ramanujan (Mathematician - 1), Sir C.V. Raman (Physicist - 4), and Sir J.C. Bose (Physicist-Botanist - 3). This corresponds to the code (a)-2, (b)-1, (c)-4, (d)-3, which is option 2.
