Folk forms in prints means the use of folk imagery, rural symbols, traditional motifs, local figures, popular visual culture and indigenous forms in printmaking.
Step 1: Check Laxma Goud.
Laxma Goud is known for using folk, rural and regional imagery in his prints and drawings.
His works often show village life, human figures, animals and folk-inspired forms.
So:
\[
B = \text{Correct}
\]
Step 2: Check Jyothi Bhatt.
Jyothi Bhatt is known for printmaking, painting and photography.
He documented and used folk and traditional visual forms in his works.
So:
\[
D = \text{Correct}
\]
Step 3: Eliminate other artists.
Devraj Dakoji and Gulam Sheikh are important modern artists, but the correct pair in this question is Laxma Goud and Jyothi Bhatt.
Amrita Shergill is mainly known as a modern painter, not as a printmaker using folk forms in this context.
Step 4: Final conclusion.
The artists who used folk forms in prints are:
\[
B,\ D
\]
Hence:
\[
\boxed{\text{(B) B and D only}}
\]
